Acid house party

An acid house party was a type of illegal party typically staged in abandoned warehouses between 1987 and 1989. Parties played acid house and acid techno music, electronic music genres with a distinct sound from the use of the Roland TB-303 synthesizer. The origin of the term acid house party is disputed coming either from the 1987 song "Acid Tracks" by Phuture, or the consumption of MDMA and LSD that were common at the parties.
