Madchester was a musical and cultural scene that developed in the English city of Manchester in the late 1980s, closely associated with the indie dance scene. Indie-dance saw artists merging indie music with elements of acid house, psychedelia and 1960s pop. The term Madchester was coined by Factory Records' Tony Wilson, with the label popularised by the British music press in the early 1990s, and its most famous groups include the Stone Roses, Happy Mondays, Inspiral Carpets, the Charlatans, James and 808 State. It is widely seen as being heavily influenced by drugs, especially MDMA. At that time, the Haçienda nightclub, co-owned by members of New Order, was a major catalyst for the distinctive musical ethos in the city that was called the Second Summer of Love.

Acid house 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.
