Beat 13 are a collective of artists and musicians based in Birmingham who’ve been doing stuff since around 1999. Founded by Matt Watkins and Lucy Mclauchlan the emphasis appears to be on Lucy’s work which you’ve probably seen about the place at some point or other.
While they were very active in 2006 the website has that verging-on-the-ghost feel to it so I’m not sure what’s going on with them right now. Hopefully lots of interesting things.
