Bristol has long been the South West's rave mecca with bus loads of ravers coming to hardcore nights from lesser endowed cities like Bournemouth and Bath since the nineties. At the heart of Bristol's hardcore and old skool scene has always been Lakota, the only venue (until recently) large enough for huge, multi-room raves. The venue's industrial warehouse feel and non-central location also made it popular with Bristol's free party crews who's multi-rig 'linkups' (most notably the Gener8r parties) have also made Bristol a national attraction for oldskool, mash-up and breakcore nights.
The Black Swan in Easton is Bristol's other key rave venue, attracting promoters like Mongrel (formerly at the Croft), Tiki and Avalaf. Keep an eye on Lab's listings for occasional Wrong Music events and even check Whats on at Bristol's Motion for the odd large rave event like Battlegrounds.
