Derek is, oddly enough, the son of Allman Brothers drummer Butch Trucks. I say "oddly' because he's a slide guitarist who plays like the second coming of Duane Allman rather than his drummer father. Here he is at only 13 years of age playing like a man of 50:
Derek is 34 now and married to singer/songwriter Susan Tedeschi. (A more perfect match I've never seen.) They perform together most of the time these days, but Derek still plays with the Allman Brothers Band quite a bit too. Here they both are with the ABB backing them on the old Bob Dylan song, Don't Think Twice. Derek's solo starts at 3:17. He gets better every year.
