Pretty much the same stuff as last time this thread came up, hardcore banging German techno, the sort of stuff you listen to while killing people...
Also listening to:
Luke Slater - Fear & Loathing vol. 2
Dave Clark - World Service
Prodigy - Music For The Jilted Generation
Chemical Brothers - Dig Your Own Hole
and any techno by the likes of DJ Rush, Felix Kroecher and DJ Murphy.
Also getting into weird acid house stuff by Chris Liberator and Dave Drummer, its not hard house, its not techno, its somewhere in between....
