I would disagree somewhat with calling them"a bit of a one trick pony".I have six LPs by them on vinyl "The Big Come UP" (white vinyl),"Thickfreakness","The Rubber Factory",Magic Potion","Chulahoma" and "Attack & Release".The albums show a continuity and pattern of growth.Chulahoma on Fat Possum is an LP of straight covers of Junior Kimbrough who served as inspiration to Dan Auerbach (guitar,vocals).There's a DVD of live material which shows what an incredible amount of sound can be generated by two guys.The new LP Attack & Release is half speed mastered,and comes with full CD of the album enclosed for those who have use for it.The new LP is a slight departure from the road they have been on.Outside production by Danger Mouse and less overt blues emphasis.Would I put them aside for Muddy? Sure,but you can't listen to Muddy and Kid Prince Moore all day.These guys impressed me with their first LP and I kinda like having some young turks around carrying on the tradition with covers of Robert Pete Williams,Eddie Cochran,Kimbrough and even Lennon mcCartney as well as their own contributions.
