I've got to say there are some killer nights in Bristol- 666, Ripsnorter, And others. The Black Swan on the Stapleton Road can be a good venue depending on what the promoters make of it- the Trinity centre was pretty cool on NYE but you wouldn't want anymore than about 550 people in there, The Lakota can have some good nights on- if you can put up with the sh*tty attitudes of the security and bar staff. Try and get hold of a copy of Out of Hand (should be able to get one from Bristol Ticket Shop in the Arcade), which has flyers and listings for most promoters and venues around Bristol. You could, of course, try a little further afield and try Toadstool in Gloucester
