We might not know for sure until later this month, but there's a chance the Rolling Stones are headlining Coachella this year. The rumor stems from Coachella mysteriously posting a Facebook photo (below) of a big round rock in an empty field on the festival's grounds. That thing would roll.
There's also this, per Rolling Stone (the magazine, not the band or the photographed stone): "The Stones themselves listed Coachella 2013 in the tour section of their mobile app for a brief time late last year, though Mick Jagger told Rolling Stone that he didn't know how it got there." Hmm…
The Stones haven't played an American festival since 1969, when they were at Altamont. The band is priming up for a lot more shows this year, though, having only played a small handful of late 2012 concerts to honor their 50th anniversary. "We barely got off the starting blocks," Keith Richards said.
Other legacy acts Coachella has brought in include Morrissey in 1999 and 2009, Paul McCartney in '09, The Cure in '04, Depeche Mode in '06, Roger Waters in '08, and Siouxsie & the Banshees in '02. The Stones would certainly be a landmark headliner for the festival, especially considering they'd likely play both of the fest's identical weekends in April.
