Hard rock is my "go to" for music. Tool's my favorite band. Sevendust is a close second. followed by Pantera. But I dig it all.
Not much on modern hip hop because there's usually not much there, cerebrally speaking. Lyrics mean a lot to me, and if the deepest you go is blow, booty, and booze, then I'm not with it. But I dig almost everything else.
Old school hip hop, R&B, classical, blues, light and airy favorites, classic rock, I have Jim Croce on CD. I also have Duke Ellington. Pat Martino is a hell of a jazz guitarist. I have almost every Digital Underground album ever recorded. Same goes for Black Crowes and Tower of Power. I like drinking my coffee in my courtyard while I listen to Chopin. Portishead and Tori Amos are awesome. Massive Attack is cool as hell.
Too much good stuff out there to box myself in.
