Overview
Acid house (also simply known as just "acid") is a subgenre of house music developed around the mid-1980s by DJs from Chicago. The style is defined primarily by the squelching sounds and basslines of the Roland TB-303 electronic bass synthesizer-sequencer, an innovation attributed to Chicago artists Phuture and Sleezy D circa 1986.
Acid house soon became popular in the United Kingdom and continental Europe, where it was played by DJs in the acid house and later rave scenes. By the late 1980s, acid house had moved into the British mainstream, where it had some influence on pop and dance styles.
Acid house brought house music to a worldwide audience. The influence of acid house can be heard in later styles of dance music including trance, hardcore, jungle, big beat, techno and trip hop.
Characteristics
Acid house's minimalist sound combined house music's ubiquitous programmed four-on-the-floor 4/4 beat with the electronic squelch sound produced by the Roland TB-303 electronic synthesizer-sequencer. The sound is commonly produced by raising the filter resonance and lowering the cutoff frequency of the synthesizer, along with programming the 303's accent, slide, and octave parameters, to create variation in otherwise simple bass patterns. "Exploration of texture" is preferred over melody; "a refusal of the metaphysical priorities of western music discourse." Other elements, such as synthetic strings and stabs, were usually minimal. Sometimes tracks were instrumentals such as Phuture's "Acid Tracks", or contained full vocal performances such as Pierre's Pfantasy Club's "Fantasy Girl", while others were essentially instrumentals complemented by the odd spoken word 'drop-in', such as Phuture's "Slam".
