The Gene Generation. Awesome post-apocalyptic/cyberpunk movie featuring music by Combichrist and Ronan Harris.
Cool I'm gonna have to check that out. Sounds like my kind of music atleast :P
Also I kinda stumbled over an old John Carpenter movie on a lovecraft related channel on youtube. It was called The Mouth of Madness and I really liked it.
Just don't go into it expecting an oscar winner. It's plot is kinda pieced together strangely and Bai Ling is topless for a bunch of scenes (This may be a good OR bad thing depending on your outlook). I can't really describe alot of it, but combine a gothic/industrial look with a cyberpunk world, and you have this. Think Shadowrun meets the masters cathedral from Fallout, with a hint of Hell from Doom 3.
That said, it's soundtrack kicks major ass and I had a fun time watching it.
