Passage: Soul and disco influenced house music, plus mixing and editing techniques earlier explored by disco, garage music and post-disco DJs, producers, and audio engineers such as Walter Gibbons, Tom Moulton, Jim Burgess, Larry Levan, Ron Hardy, M & M, and others who produced longer, more repetitive, and percussive arrangements of existing disco recordings.
