Goldenvoice, the promoter behind Coachella Valley Music & Arts Festival in Indio, CA just dropped a hint that is not going ignored.

The festival’s April 12th date appeared on The Stones’ official iPhone app in December but was quickly pulled, appearing to be a glitch. Jagger claims now to know nothing of the Coachella appearance – but the Indio, California festival itself is hinting otherwise. Last night, Coachella’s continuing set of lineup clues rolled out a curious photo showing a round object nestled in middle of the Empire Polo Field. Is that a rolling stone? Check out the photo below, via Coachella’s Facebook page.

According to Rolling Stone, The Stones have not played a formal festival gig in the U.S. since Northern California’s Altamont Speedway Festival in 1969.
