Allman Brothers Band

Technically, the Allman Brothers Band hasn't existed since guitarist Duane Allman died in October 1971. But the group forged on after his death, and, more than three decades later, the pioneering Southern-rock institution is still keeping pace with the packs of protegés it's spawned while fostering a loyal fan base that rivals the legions who celebrate the once-grateful Dead. In recent years, the Allmans has been infused with energy from the prodigious Derek Trucks and guitarist Warren Haynes, both of whom have helped take its trademark double-lead sound to new heights. And as long as Gregg Allman is holding court on the organ, a lifeline to the band's founding spirit remains, no matter whose names fall under the Allman Brothers on the marquee.
