A few years ago I stumbled onto a website that had totally kick ass backing tracks, sounded 98% original. They were not free, but they were really good. The catalog was a bit limited at the time but they had bands like Dream Theater and other prog rock bands, maybe some Genesis, can't really remember. I'm just looking to buy some tracks that I can incorporate into some small live gigs I will be doing. Looking for tracks where you can mute the bass, keyboards, vocals, etc.
