Been listening to a lot of stoner rock / metal recently I didn't know I had (courtesy of a friend long ago). Ie Kyuss, Lowrider, some Queens of Stone Age. Sounds good on an ol timely Conrad Johnson MV75a1 tube amp I'm trying out. Thanks to someone on this thread some time back that recomended Trouble, a band I previously was unaware of that rocks!
Rage Against the Machine's Live at Olympic Stadium is an ass kicking album, regardless of whether it can be considered "metal" or not. I'm ambivalent about some of their other albums, but not that one.
