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.

Deep house is a subgenre of house music that originated in the 1980s, initially fusing elements of Chicago house with 1980s jazz-funk and touches of soul music. Its origins are attributed to Larry Heard’s track “Mystery of Love” in 1984.This style of house music can often have an acoustic feeling. The online music store Beatport is credited with driving the popularity of deep house, but also with mislabeling a number of artists in the process and with giving rise to the future house genre.

A house is a building that functions as a home. They can range from simple dwellings such as rudimentary huts of nomadic tribes and the improvised shacks in shantytowns to complex, fixed structures of wood, brick, concrete or other materials containing plumbing, ventilation, and electrical systems. Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock (like cattle) may share part of the house with humans. The social unit that lives in a house is known as a household.
Most commonly, a household is a family unit of some kind, although households may also be other social groups, such as roommates or, in a rooming house, unconnected individuals. Some houses only have a dwelling space for one family or similar-sized group; larger houses called townhouses or row houses may contain numerous family dwellings in the same structure. A house may be accompanied by outbuildings, such as a garage for vehicles or a shed for gardening equipment and tools. A house may have a backyard or frontyard, which serve as additional areas where inhabitants can relax or eat.

Dark ambient (especially in the 1980s referred to as ambient industrial) is a genre of post-industrial music that features an ominous, dark droning and often gloomy, monumental or catacombal atmosphere, partially with discordant overtones. It shows similarities towards ambient music, a genre that has been cited as a main influence by many dark ambient artists, both conceptually and compositionally. Although mostly electronically generated, dark ambient also includes the sampling of hand-played instruments and semi-acoustic recording procedures, and is strongly related to ritual industrial music.

Post-disco is a term to describe an aftermath in popular music history circa 1979–1986, imprecisely beginning with an unprecedented backlash against disco music in the United States, leading to civil unrest and a riot in Chicago known as the Disco Demolition Night on July 12, 1979, and indistinctly ending with the mainstream appearance of house music in the late 1980s. Disco during its dying stage displayed an increasingly electronic character that soon served as a stepping stone to new wave, old-school hip hop, euro disco and was succeeded by an underground club music called hi-NRG, which was its direct continuation.
An underground movement of disco music, “stripped-down”, and featuring “radically different sounds” took place on the East Coast that “was neither disco and neither R&B”, This scene known as post-disco catering to New York metropolitan area, was initially led by urban contemporary artists partially in response to the over-commercialization and artistic downfall of disco culture. Developed from the rhythm and blues sound as perfected by Parliament-Funkadelic, the electronic side of disco, dub music techniques, and other genres. Post-disco was typified by New York City music groups like “D” Train and Unlimited Touch who followed a more urban approach while others, like Material and ESG, a more experimental one. Post-disco was, like disco, singles-driven market controlled mostly by independent record companies that generated a cross-over chart success all through the early-to-mid 1980s. Most creative control was in the hands of record producers and club DJs which was a trend that outlived the dance-pop era.
Other musical styles that emerged in the post-disco era include dance-pop, boogie, and Italo disco and led to the development of the early alternative dance, club-centered house and techno music.
