Yeah, Warren is great, but I find myself listening much more closely to what Trucks is doing, even his vamping. There is a very interesting show from the 2005 batch of Instant Lives (Philly) that has Trucks as the only guitarist, because Warren had to attend to "family problems". So you get to hear Derek Trucks play all of the guitar parts, which is very cool, and there is a version of Dreams with both Trucks and Ron Holloway (on tenor) soloing. This show is a must hear!
