Progressive house is a style (subgenre) of house music. The progressive house style emerged in the early 1990s. It initially developed in the United Kingdom as a natural progression of American and European house music of the late 1980s.

Alternative rock (also called alternative music, alt-rock or simply alternative) is a style of rock music that emerged from the independent music underground of the 1980s and became widely popular in the 1990s. In this instance, the word “alternative” refers to the genre’s distinction from mainstream rock music. The term’s original meaning was broader, referring to a generation of musicians unified by their collective debt to either the musical style or simply the independent, DIY ethos of punk rock, which in the late 1970s laid the groundwork for alternative music. At times, “alternative” has been used as a catch-all description for music from underground rock artists that receives mainstream recognition, or for any music, whether rock or not, that is seen to be descended from punk rock (including some examples of punk itself, as well as new wave, and post-punk). Although the genre evolved in the late 1970s and 1980s, music anticipating the sound of the genre can be found as early as the 1960s, with bands such as The Velvet Underground.
Alternative rock broadly consists of music that differs greatly in terms of its sound, social context and regional roots. By the end of the 1980s, magazines and zines, college radio airplay, and word of mouth had increased the prominence and highlighted the diversity of alternative rock, helping to define a number of distinct styles (and music scenes) such as noise pop, indie rock, grunge, and shoegaze. Most of these subgenres had achieved minor mainstream notice and a few bands representing them, such as Hüsker Dü and R.E.M., had even signed to major labels. But most alternative bands’ commercial success was limited in comparison to other genres of rock and pop music at the time, and most acts remained signed to independent labels and received relatively little attention from mainstream radio, television, or newspapers. With the breakthrough of Nirvana and the popularity of the grunge and Britpop movements in the 1990s, alternative rock entered the musical mainstream and many alternative bands became successful.

Witch House is a fantasy novel by American writer Evangeline Walton. It was published in 1945 by Arkham House in an edition of 3,000 copies. It was the first full-length novel to be published by Arkham House and was listed as the initial book in the Library of Arkham House Novels of Fantasy and Terror. An expanded version, with a newly-written 20,000-word prologue, was published in England in 1950. In 2013, Centipede Press issued the first American edition of this revised version, also including previously unpublished writings by Walton and several of her short stories.According to Robert Weinberg, the volume was Arkham House’s greatest flop – an excellent novel that took nearly two decades to go out of print.E. F. Bleiler described the novel as a “Neo-Gothic thriller… [marked by] imaginative writing, a good climax, but a prolonged, dull first section and characterizations that do not click.” The Encyclopedia of Fantasy found it to be “an atmospheric Haunted-Dwelling tale”.

Rapping (or rhyming, spitting, emceeing, MCing) is a musical form of vocal delivery that incorporates “rhyme, rhythmic speech, and street vernacular”, which is performed or chanted in a variety of ways, usually over a backing beat or musical accompaniment. The components of rap include “content” (what is being said), “flow” (rhythm, rhyme), and “delivery” (cadence, tone). Rap differs from spoken-word poetry in that rap is usually performed in time to an instrumental track. Rap is often associated with, and is a primary ingredient of hip-hop music, but the origins of the phenomenon predate hip-hop culture. The earliest precursor to the modern rap is the West African griot tradition, in which “oral historians”, or “praise-singers”, would disseminate oral traditions and genealogies, or use their formidable rhetorical techniques for gossip or to “praise or critique individuals.” Griot traditions connect to rap along a lineage of Black verbal reverence that goes back to ancient Egyptian practices, through James Brown interacting with the crowd and the band between songs, to Muhammad Ali’s quick-witted verbal taunts and the palpitating poems of the Last Poets. Therefore, rap lyrics and music are part of the “Black rhetorical continuum”, and aim to reuse elements of past traditions while expanding upon them through “creative use of language and rhetorical styles and strategies. The person credited with originating the style of “delivering rhymes over extensive music”, that would become known as rap, was Anthony “DJ Hollywood” Holloway from Harlem, New York.Rap is usually delivered over a beat, typically provided by a DJ, turntablist, beatboxer, or performed a cappella without accompaniment. Stylistically, rap occupies a gray area between speech, prose, poetry, and singing. The word, which predates the musical form, originally meant “to lightly strike”, and is now used to describe quick speech or repartee. The word had been used in British English since the 16th century. It was part of the African American dialect of English in the 1960s meaning “to converse”, and very soon after that in its present usage as a term denoting the musical style. Today, the term rap is so closely associated with hip-hop music that many writers use the terms interchangeably.

Underground hip hop is an umbrella term for hip hop music outside the general commercial canon. It is typically associated with independent artists, signed to independent labels or no label at all. Underground hip hop is often characterized by socially conscious, positive, or anti-commercial lyrics. However, there is no unifying or universal theme – AllMusic suggests that it “has no sonic signifiers”. “The Underground” also refers to the community of musicians, fans and others that support non-commercial, or independent music. Music scenes with strong ties to underground hip hop include alternative hip hop and conscious hip hop. Many artists who are considered “underground” today were not always so, and may have previously broken the Billboard charts.To gain fans, underground artists perform locally and worldwide, make tours, and meet and greets. Their performances are held anywhere, such as outdoors or in restaurants. Meet and greets are often held in different cities, which gives a fan the opportunity to meet the artist for free. There the fan can buy clothing from the artist’s clothing line or they can purchase tickets for future concerts. Ticket prices range depending on the location, some artists have VIP passes, allowing the fan to have access to the stage and to meet them after the show. Some artists make their own clothing line to sell gear and use the profit to continue making shows. Underground artists are usually found in YouTube, SoundClick, Bandcamp and SoundCloud. Lastly, underground artists typically do everything themselves whether it’s making songs, preparing shows, or selling gear.

Electronic dance music (EDM), also known as dance music, club music, or simply dance, is a broad range of percussive electronic music genres made largely for nightclubs, raves and festivals. It is generally produced for playback by disc jockeys who create seamless selections of tracks, called a mix by segueing from one recording to another. EDM producers also perform their music live in a concert or festival setting in what is sometimes called a live PA. In Europe, EDM is more commonly called ‘dance music’, or simply ‘dance’.In the late 1980s and early 1990s, following the emergence of raving, pirate radios and an upsurge of interest in club culture, EDM achieved widespread mainstream popularity in Europe. In the United States at that time, acceptance of dance culture was not universal; although both electro and Chicago house music were influential both in Europe and the United States, mainstream media outlets and the record industry remained openly hostile to it. There was also a perceived association between EDM and drug culture, which led governments at state and city level to enact laws and policies intended to halt the spread of rave culture.Subsequently, in the new millennium, the popularity of EDM increased globally, largely in Australia and the United States. By the early 2010s, the term “electronic dance music” and the initialism “EDM” was being pushed by the American music industry and music press in an effort to rebrand American rave culture. “Despite the industry’s attempt to create a specific EDM brand, the initialism remains in use as an umbrella term for multiple genres, including house, techno, trance, drum and bass, dubstep, and Trap music (EDM) as well as their respective subgenres.[5][6][7][8][9]”

Dubstep is a genre of electronic dance music that originated in South London in the late 1990s. It is generally characterized by sparse, syncopated rhythmic patterns with prominent (and often wobbly) sub-bass frequencies and epic breakdowns. The style emerged as an offshoot of UK garage, drawing on a lineage of related styles such as 2-step and dub reggae, as well as jungle, broken beat, and grime. In the United Kingdom, the origins of the genre can be traced back to the growth of the Jamaican sound system party scene in the early 1980s.The earliest dubstep releases date back to 1998; they were usually featured as B-sides of 2-step garage single releases. Early tracks were darker, more experimental remixes with less emphasis on vocals, instead attempting to incorporate elements of breakbeat and drum and bass into 2-step. In 2001, this and other strains of garage music began to be showcased and promoted at London’s night club Plastic People, at the “Forward” night (sometimes stylised as FWD>>), which went on to be considerably influential to the development of dubstep. The term “dubstep” in reference to a genre of music began to be used by around 2002 by labels such as Big Apple, Ammunition, and Tempa, by which time stylistic trends used in creating these remixes started to become more noticeable and distinct from 2-step and grime.A very early supporter of the sound was BBC Radio 1 DJ John Peel, who started playing it from 2003 onwards. In 2004, the last year of his show, his listeners voted Distance, Digital Mystikz, and Plastician in their top 50 for the year. Dubstep started to enter mainstream British popular culture when it spread beyond small local scenes in late 2005 and early 2006; many websites devoted to the genre appeared on the Internet and aided the growth of the scene, such as dubstepforum, the download site Barefiles and blogs such as gutterbreakz. Simultaneously, the genre was receiving extensive coverage in music magazines such as The Wire and online publications such as Pitchfork, with a regular feature entitled The Month In: Grime/Dubstep. Interest in dubstep grew significantly after BBC Radio 1 DJ Mary Anne Hobbs started championing the genre, beginning with a show devoted to it (entitled “Dubstep Warz”) in January 2006.Towards the end of the 2000s and into the early 2010s, the genre started to become more commercially successful in the UK, with more singles and remixes entering the music charts. Music journalists and critics also noticed a dubstep influence in several pop artists’ work. Around this time, producers also began to fuse elements of the original dubstep sound with other influences, creating fusion genres including future garage, the slower and more experimental post-dubstep, and the harsher electro house and heavy metal influenced brostep, the latter of which greatly contributed to dubstep’s popularity in the United States.
