Johnny 5 (left) and Brer Rabbit (right).FlobotsWhere: Exhibition Hall StageWhen: Sunday, 6:00 p.m.As Bumbershoot staff began estimating that ten times more people wanted to get into the Exhibition Hall Stage to see Flobots than would be able to, the group’s explosion our of Denver’s underground really became clear. This time, there was new material and an even more polished and expanded performance — they dipped into Rage Against the Machine’s “Killing In The Name,” busted out a new I.R.A.Q. rap, and played a Turtle’s “So Happy Together” cover with their own twist. The flow was solid, the message rang true… and Brer Rabbit’s dance moves never fail to blow my mind.Mackenzie Roberts on viola.
