mrgig.com, they both seem to be mostly pub bands to me though. I would give whoever promotes the bands at Lanterns (that used to promote at Stripes), that seems to be more the style of music, and they don't seem to bother with the other local band sites. Also, The Harp Club could be a goer.
onfolkestone.co.uk1 seems to have more of the young metal crowd gigs listed, hopefully this site will have the best listings of all.
This is my site The 'Gerald that I set up in a fury of excitement when we first moved here sometime in 2004. I'd been a frequent visitor for a while before that so I am technically one of those DFLs you get nowadays. The site was a lot more dynamic with a calendar of events and voting for favourite places + things, + I hear it was a useful resource for those who were thinking of moving to the area. Now I've moved out of Folkestone again (though just to Hythe) it doesn't get as much love as it used to. Ironic really as The town is now becoming the exciting place we always thought it was just about to. I am not Gerald BTW, the name comes from a pretend paper in an episode of Brasseye or something, the Portsmouth Gerald, + how there is a local newspaper here called the Folkestone Herald. Puns like this are GRATE aren't they? Do get in touch if you have anything to offer, email anythign @ this domain, or try @folkestone or @pauly on Twitter.
