Fans were treated to a surprise appearance by Nathaniel Rateliff at Red Rocks on Saturday night, when he joined Jim James and My Morning Jacket onstage for a cover of the classic “Feelin’ Alright?” during the band’s second of two nights at the famed venue.

This follows Nathaniel Rateliff & The Night Sweats’ sold out homecoming show at Red Rocks last week. The band next plays in Denver December 15 at Ball Arena.

Watch/Share “Feelin’ Alright?”: HERE.

The video opens with the band playing live as fans cheer them on. Fifty seconds in, a cloud of smoke erupts as the audience cheers even louder. The camera zooms in on them, and then it zooms out. Two minutes in, cut to the instrumental as the band moves and dances to their own music. Nathaniel Rateliff sings again three minutes in. The audience calms down. “Feelin’ all right” repeatedly as the guitarists play closely to each other and the drummer plays passionately. Near the end of the video, all the band members face the wall. The song ends.
