Watch: Matt & Kim Go "Deep Into the Bowels" of Voodoo Fest
We followed the wild couple through City Park, where they unleashed their enthusiasm on equally-excited fans. "That was the best show I've ever seen!" one fan screamed.
The band also laughed uncontrollably/almost puked while riding the Spider, but they quickly recovered by indulging in one of America's finest delicacies: a festival funnel cake.
Watch all the festival fun with Matt & Kim above, and check out everything else that happened at Voodoo.
