'Expansions' reaches its 50th anniversary of recording this year. The ground-breaking jazz funk track is one of the most influential records in club music, being a dancefloor hit in the UK and New York on release, and going on to be a foundation piece for club culture. It has been sampled, quoted and remade and now for the first time the full length version is available on a 7-inch single. It is paired with ‘Cosmic Funk’.
