So I was just reading all the posts about learning to solo/lead/improv better and what-not, and I was wondering if anybody knew of a site or sites where somebody could download music without a lead specifically designed for people to practice soloing over. Kind of like practicing and jamming with a band without the rest of the band. I know it'd be easy to make this sort of thing myself, but I just figured it'd be neat to see what's out there and see if anybody knew of some good sites with this sorta thing. Any insight is appreciated.
