Sidewinder, the seminal club night and all-round underground music hub, has been going for almost 20 years now. Birthed just outside of London, in Northampton, the brainchild of promoters Mark Lambert and Paul Spruce is considered something of a national grime treasure today — and remains one of the most-loved (and attended) bass-heavy raves around. Sidewinder’s hosted some of the biggest and best names in UK garage, grime, dubstep and bassline/4x4 on their stages, and they have the DVDs and tape-packs to prove it, too. Paul Spruce, one of the scene’s unsung heroes, gives Complex a personal account of the past, present, and future of this British institution.
