Lesser musicians, however, often make ridiculous claims in the liner notes as to their ability to catapult listeners into advanced spiritual states through specially designed sonic vibrations and "immaculately conceived" musical ideas. Disco
While undanceable hard rock and introspective singer/songwriters seemed to reign during the first half of the 70s, the predominately gay Manhattan discotheque (French for "record library") scene increasingly gained prominence as the purveyors of the type of music eventually called disco, which set out to celebrate one thing: dancing. One of disco's signature qualities was its steady kick-drum-heavy beat. By the late 70s, the genre had become essentially a producer's medium, where the singer's personality was secondary to the groove. Gamble & Huff's glossy production style helped score a considerable number of hits for artist like the O'Jays, Harold Melvin & the Blue Notes, the Intruders, and the Three Degrees. Giogio Moroder's clinical synth-heavy approach launched Donna Summer's career. (Summer eventually went beyond disco into major pop success.) In 1977 disco reached its commercial zenith with the 24-million-selling soundtrack to the movie Saturday Night Fever, which featured the Bee Gees, Tramps, Tavares, KC & the Sunshine Band, Kool & the Gang, MFSB, and others. Other significant disco artists included Shalamar, George McCrae, Chic, Village People, Sister Sledge, Sylvester, and Barry White. Disco's dominance of the late-70s popular-music landscape was so pervasive that even the sound of such artists as Herbie Hancock and the Rolling Stones incorporated its thumping grooves.

Dance-Pop
At the top of the 1980s, disco had more than worn out its welcome with many people, so disco's rigid 4/4 groove was replaced by more elastic rhythms and varied synth and other instrumental arrangements. Like disco, much dance-pop is a producer's medium. In a sense, disco never died; it just changed clothes. Over the course of the 80s and 90s, this form of music has remained extremely popular.Examples: Michael Jackson, Janet Jackson, Prince, Madonna, Paula Abdul, and Whitney Houston. Techno-Pop/Dance
Techno's roots can be traced to the 70s synthesizer experiments of Tangerine Dream, Kraftwerk, and Brian Eno. David Bowie and Roxy Music aided in the cool, arty pop sensibilities that have informed this subgenre.Examples: Ultravox, Depeche Mode, Blue Nile, Human League, Yello, New Order, and Marc Almond.--.
