pdn is right about D.T.-he's butch trucks' nephew---he's had his own band for several years, and has toured with the allman bros numerous times. i've seen him live lots of times, 3 of which were with the allmans...
the first time i saw him he was 13 years old...and VERY impressive for such a young dude. his gibson SG was huge on him! most recent time i saw him was last summer (august 07) on the allman bros tour...his playing had matured noticably, really vastly improved. maybe hanging out with warren haynes has helped him round out his expertise...he seemed more relaxed than ever, just willing to sit back and not overplay, deferring to warren... really jelled with the band better than ever before.
derek trucks and warren haynes together are a tour-de-force, for sure! the allman bros always come out to play. if you love their music, don't pass up a chance to catch them live...derek and warren will probably be there.
never listened to any D.T. records, but the live experience has been great...his wife susan tedeschi is fantastic also!
seen her perform twice...lotta talent between the two of them.
