Got some decent London gig contacts but now looking to do some outside the capital and was wondering if any of you kind folks could suggest venues to try? Either unsigned nites a la Dublin Castle/Water Rats or else support slots for bigger bands...

Sorry if this has been done before like, but any tips for these places gratefully received, as well as any cties or towns I may have missed out. Cheers!
