I've been listening to a lot of Front Line Assembly lately. I'm into collecting vinyl from the Wax Trax days, but I recently became really impressed with how FLA has evolved significantly over the years. They've really become masters of their craft - I couldn't believe it. Try putting on the Warmech or Airmech albums and just letting them play ambiently in the background.
I guess they are video game sound tracks, but honestly they sound like artsy industrial club albums.
