If you've seen a Jack White show in the past year, you've either caught the former White Stripes frontman playing with the Peacocks, White's all-female band or the Buzzards, his all-male group. On tour, the singer alternates backing bands, allowing music nerds like us to debate the merits of each and have another "Who's better?" argument to fight over. Not tonight! For the singer's headlining set, White swapped bands halfway through his two-hour performance, substituting the Buzzards for the Peacocks in a rare switch. When you have a platform as big as Lollapalooza, you can't be greedy. Nice work, Jack.
