Gov't MuleWarren Haynes joined the Allman Brothers Band in 1989, and was a member of the Dead for its 2004 and 2009 tours.

But Haynes, who was 23rd on Rolling Stone's 2003 list of the 100 greatest guitarists of all time, suggested in a phone interview this week that Gov't Mule is dearest to his heart, despite the legendary status of his other bands. He co-founded Gov't Mule in 1994 as an Allman offshoot, and he said it offers an unparalleled freedom.

"Gov't Mule is our laboratory to create anything musically that we want to create," he said. "We're still establishing the parameters. In in a band like the Allman Brothers or the Grateful Dead, they're pretty open-minded about what the music can be, but there are parameters that were established a long time ago ... ."

Gov't Mule will perform at the Capitol Theatre in downtown Davenport on Tuesday, February 9, and Haynes said the quartet has a newfound energy. It's evident on the band's album from last year -- By a Thread -- and in its live shows, and he credited that change to bassist Jorgen Carlsson, who joined a year and a half ago.
