The band played 32 songs, including new tracks "Run" and "The Sky Is a Neighborhood," from their upcoming album, Concrete and Gold, out Sept. 15. Fans were also treated to a special appearance by Lollapalooza founder and Jane's Addiction frontman Perry Farrell, who joined the band to perform "Mountain Song."
