I'd imagine that it gets played at the turnaround, which is the last friday of each month at galatos I think. Also people like Cian, Stinky Jim, Manuel Bundy, etc play this stuff round town.
Work on saturday mornings means I havent been there to check it myself
I havent listened to it, but 'Richard Dorfmeister presents A Different Drummer Selection' sounds good just from the title.

If you are just sick of mainstream american hiphop theres some good stuff out from Anticon and Def Jux labels, also really good is the Prefuse 73 album 'One Word Extinguisher'.
