The 2022 Stern Grove Festival lineup was announced Friday in a small masterwork of accidental marketing genius: placing an ad on a Muni bus and letting the public do the rest.

The lineup includes headliners Liz Phair (June 26), Cat Power (July 17), Phil Lesh & Friends (Aug. 14), Tower of Power and Too Short (June 12), Leann Rimes (July 24), Taj Mahal (Aug. 7), Old Crow Medicine Show (July 17) and the SF Symphony (July 31), according to the Muni ad.

The ad in question, first reported by the San Francisco Chronicle, notes that all performances for the festival's 85th season will still be free. Advance reservations for entry, added in in recent years, will again be required.

KQED has reached out to the festival to confirm the lineup in the Muni bus ad.

Photos of the ad surfaced on Reddit and other social media on Friday, giving organizers at the Stern Grove Festival either a) extreme frustration at the leaked lineup, not planned for release until May 3, or b) a scramble to try and put a positive spin on the situation.
