The Never Ending Pool

That's Dave Matthews Band for those who didn't know. They often close their shows with a cover of Watchtower. This one's my favorite of their performances of it. The first solo is taken by violinist Boyd Tinsley, who plays it pizzicato, the second by saxophonist LeRoi Moore, the third by Warren Haynes (of Gov't Mule and Allman Brothers Band fame) guesting on slide guitar, and the fourth by Tim Reynolds, who played lead guitar for them back in the day (and may be returning to the band this year). Check it out, it WILL blow you away.
