Never heard 'em with Betts, let alone with Duane. Heard lots of records, however, and many are terrific, especially Fillmore, which I think is as good a live album as has ever been done. And I will even admit that Derek Trucks's got an annoying habit of running his slide back down the neck every phrase or two that sometimes makes me wince; and I'm not a big fan of Warren Haynes's voice for that matter. That said, I've seen the current line-up several times, and they kick ass. If they don't have the original magic, they have some other magic. Every one is a fantastic musician, and they play hard and great together. All substance, no posing. Go hear 'em.
