Groove (film)

Groove is a 2000 American film that portrays one night in the San Francisco underground rave scene. Through a single email, the word spreads that a huge rave is going to take place in an abandoned warehouse. John Digweed has a cameo as himself and also contributed to the soundtrack with Nick Muir, under their production alias Bedrock.

After being turned down by studios for funding, production costs were met by selling shares of the film to investors similar to angel investment of a startup company.
