I've just moved to a town that is having a Blues Festival this weekend. The headlining act is Pinetop Perkins. Now I've just started listening to the blues and have heard that name, but don't know anything about him (not even what instrument he plays), but I seem to remember he's pretty old. Can anyone tell me if he's still worth going to see? Will this be one of those missed opportunities I'll regret later in life if I don't go?
