Back to headline Weekend 2, the Red Hot Chili Peppers closed out this year's Austin City Limits Music Festival with a bang of a performance that had a sea of fans stretched across the lawn in front of the American Express stage.

Toward the start of the band’s set, there was a notable hiccup. Fans standing from about the American Express Experience area and back were shouting that they could not hear much of the music and yelled for the sound to be fixed.

“Turn it up, turn it up, turn it up,” the crowd screamed.
