AUSTIN, TEXAS - Minneapolis-reared all-star indie-rock group Gayngs had to cancel its show Sunday afternoon at the Austin City Limits Festival -- the biggest gig of its short existence -- after its tour bus reportedly left town without the members, but with all of its music gear in tow.

Featuring members of Solid Gold, Bon Iver, Doomtree and Megafaun, the band performed Saturday night at Emo's nightclub in downtown Austin and had less than a mile to travel to its gig the next afternoon on the ACL Festival grounds. Somewhere along the way, though, the bus disappeared, the band said. It was not clear if the driver took off with it, or someone else did. The band reported it stolen at 4:20 a.m.

"We are insanely bummed out by these events," the band said in a statement.

The members reportedly spent a sleepless night and morning trying to find suitable replacement gear, to no avail. They were part of an eclectic ACL lineup Sunday that included the Eagles, Flaming Lips, Band of Horses, Norah Jones and the National for one of the country's biggest festivals, with about 70,000 daily attendees.

Talking before its Saturday night gig, Gayngs leader Ryan Olson boasted about how the band's two-week tour -- which also included an appearance on NBC's "Late Night With Jimmy Fallon" -- "turned us into a living, breathing band." The ACL gig was supposed to be its big finish before its members returned to their full-time groups.

"It's been ridiculously fun, but this is probably it," Olson said Saturday.

Too bad his band would be robbed of its finale.
