Watch a slideshow of The Black Keys at Bumbershoot. Renee McMahonWho: The Black KeysWhere: MainstageWhen: 8:30ishDan Auerbach plays the rhythm, the lead and the baseline all at the same time. I had never really thought about this until a buddy was surprised to see that the Black Keys comprise only two members. Hearing it is one thing, but to see Auerbach do it live was pretty damn cool. These guys throw an amazing rock show and honestly, after day number two, I’ll say it: Theirs was my favorite set. I don’t think it’ll be topped. The boys from Akron keep it too filthy.
