Disco

Shedding the political themes and global concerns that charged 1960s rock, Disco emerged in the '70s as pure dance-based music, with heavy beats standing above all other elements. Producers like Giorgio Moroder and Van "The Hustle" McCoy manned the boards -- and in some cases performed -- on numerous hits. Most Disco records were cut specifically for clubs to maintain an anonymous, free-spirited vibe. Exceptions to this rule included Donna Summer, Bee Gees, and KC & the Sunshine Band. Disco dissolved in the '80s, but its influence is still felt strongly in subgenres like Dance Pop, House and Techno.
