Music fans who attended the third and final day of this weekend's Austin City Limits Music Festival in Texas were left filthy and smelly when heavy rain obliterated the Zilker Park site, and brought sewage to the surface.
According to local newspaper the Austin-American Statesman, organisers have shut the park down for two weeks as they work to revamp newly-laid grassland ruined by festivalgoers.
Reports suggest fans who stayed to watch Sunday night headliners Pearl Jam were hit by the stench of compost laid underneath the grass in the weeks leading up to the event.
One festivalgoer says, Friday was a perfect day - sunshine and blue skies but then the rains came and, by Sunday, the place had turned into a bog."
Pearl Jam made sure the faithful who put up with the smell and the mud were treated to a memorable set, bringing Ben Harper and Perry Farrell up to join them onstage.
Harper joined the band for a rendition of Red Mosquito, while Farrell took over lead vocals for a cover of his act Jane's Addiction's Mountain Song.
Jack White's band the Dead Weather, the Arctic Monkeys and Spearhead were among the other groups who performed amid the mud on Sunday.
The three-day festival also featured Kings of Leon, Dave Matthews Band, Dave Grohl's supergroup Them Crooked Vultures and the Yeah Yeah Yeahs.
