Alabama Shakes teamed up with Prince last night during their performance at the Purple One’s Paisley Park studio in Chanhassen, Minnesota. While no video of the collaboration has made its way into the world—a consequence of Prince’s longstanding policy against such things—people on Twitter have reported that the rocker jumped on stage with the band for a 15-minute jam session during “Gimme All Your Love.”

Alabama Shakes will continue their tour tomorrow night with a show at Detroit’s Masonic Temple, and Prince will continue his tour whenever he feels like it.
