Currently I got on the collection i picked up from the wychwood festival

which consists of

Alabama 3 - Outlaw

Show of hands - As You Were (The live CD of the Autumn tour 2004)

Steve Earle - The Hard Way

mory kanté - Akwaba Beach  (personaly think it sounds a little electronic for its style)

All of these groups i saw live with Alabama 3 and Mory Kanté being the best live.
