Warren Haynes has played solo, fronted Gov’t Mule and been a member of The Dead and The Allman Brothers. His site has information, including tour dates for Gov’t Mule. Here is a nicely done bio and what seems to be a good discography.
Here are links to his recent performance at the White House, Beautifully Broken, River’s Gonna Rise and Before the Bullets Fly. Railroad Boy is acoustic. Please let me know if I’ve missed anything good.
