One of the largest of its kind.
Muddy,
You need to take a few extra days and come on down to the "Live Music Capitol of the World", Austin, Texas. We're only about 250 miles further south.
Then you can get some blues at Antone's.
About the man.......

Edit: Just this past weekend I took in Joe Ely with Double Trouble (SRV's rhythm section) in Gruene, Tx.
