my favorites are pretty much the usual suspects like Pearl Jam, Alice in Chains, Soundgarden, the Pixies, Frank Black, Dinosaur Jr, REM, and the oldies like Zep, Skynyrd, ACDC, Aerosmith, etc.
I was into 311 and Korn back in the day. I have 311's first 4 albums and the home video enlarged to show details. I was into Korn's first album until I realized that they kind of sucked after that.
and I like some thrash metal like old school Metallica, Anthrax, and Pantera.
and I also like blues like SRV, Hendrix, Gatemouth Brown, etc.
I pretty much like anything that has guitar in it.
oh, and I also love Cash, Willie Nelson, Dwight Yoakam, Randy Travis, Allan Jackson, Lyle Lovett, etc. you know, *real* country, no the fake stuff that they pass of as country nowadays.
