Marco Benevento and Superhuman Happiness ripped through 16 of David Bowie’s greatest hits at Mountain Jam this year. The tribute show was broken into two sets and was replete with guest appearances including one who is really more family than guest, Warren Haynes.

Warren came out with Marco and Superhuman Happiness for two songs to kick off the second set of the Bowie tribute. In addition to “Rebel Rebel,” Haynes helped out on “Let’s Dance.” You can watch it here, although I’ll warn you that the vocals are challenging to listen to.

Watch Warren and God Street Wine guitarist, Aaron Lieberman trade fierce guitar solos over this Bowie classic.

Thanks to Faces of Festivals for the awesome Marco photo.
