Jethro Tull Vs. The Allman Brothers Band – Ultimate Classic Rock Hall of Fame Round One

They're a rough, unshaven bunch of musical outlaws from Georgia, and all that stands between them and immortality is a British man armed with a flute. OK, we're oversimplifying things a bit, but the Allman Brothers Band and Jethro Tull are competing for your support in our 100 percent fan-voted Ultimate Classic Rock Hall of Fame bracket this month.

For more than 45 years now, flautist (look it up) and singer Ian Anderson has led Jethro Tull as they created a singular blend of acoustic-tinged progressive rock music, most notably on epic tracks such as 'Aqualung' and 'Thick as a Brick.'

For almost as long (and with one extended break), the Allman Brothers have reigned as the pioneers and kings of jam-based Southern rock. They have weathered far more than their fair share of tragedies -- including the losses of founding members Duane Allman and Berry Oakley -- and remain one of the most popular touring attractions in rock music.
