Johnny Depp is promoting his new movie “The Rum Diary” at the Austin Film Festival this week, but he found time to surprise a crowd at the Continental Club with a 90-minute performance. Who showed up? None other than ZZ Top guitarist Billy Gibbons. Check out the video of the performance below:

During the six-minute long jam, Gibbons started out with singing, but quickly introduced Depp. “We’re gonna give it to Johnny make him play that guitar,” he shouts. Depp kicks in with a pretty damn good solo, but then Gibbons takes it to another level, playing his solo with one hand, resting the other on Depp’s shoulder.
