I'm not much of a solo person when it comes to guitar. I've always loved the low end chunk sound of the guitar. But some of my fav. tunes to play are:

Pantera-Yesterday don't mean shit, I'm broken, War Nerve
Slayer-New Faith, Reining Blood
Metallica-Master of Puppets, Battery
Hatebreed-This is Now
Rage Against the Machine-Freedom, Bombtrack, Killing in the Name
Sublime-Greatest Hits

I play everything pretty much, but I love playing the heavy shit the most. Sublime is fun to play, and I LOVE playing the Blues. I don't really know any Blues acts, but I know most of the scales and such. I just improvise when I play mostly. Just go with the flow.

Peace.
