Brothers Osborne rounded out their three-night, sold-out Ryman residency on Saturday night (Feb. 16) with a performance that, as bandmate TJ Osborne promised it would at the top of the show, rocked hard and long. In fact, the setlist was so fool-proof and fast-paced that the duo wasn't taking any risk whatsoever when they waited until the second song of the encore to bring out their special guest performer.

In what was the first performance of the song they'd done together since it was recorded, the duo welcomed Lee Ann Womack to the stage to join them for "Loving Me Back," a song she'd cut with the Brothers Osborne's 2016 debut studio album, Pawn Shop. Press play above to watch the full performance.

Pawn Shop was well-represented in the duo's set list, which also included tracks like "Greener Pastures," "Rum" and "21 Summer," as well as the album's title track. The Ryman was filled with die-hards on Saturday night -- as well as friends and family, as the brothers pointed out during their set -- and the audience sang back every song.

The encore consisted of four songs, which also included "Pushing Up Daisies (Love Alive)," "Pawn Shop" and a cover of "A Little Help From My Friends" that featured opening act the Wild Feathers. While rousing, those numbers kept fairly traditional song structures compared to some of the evening's earlier performances, which featured meandering interludes and electric, several-minute-long guitar solos from bandmate John Osborne.

On the whole, the performance showcased the group's love of improvisation above all else. Amid pulsing strobe lights, crowd interaction and extended musical breakdowns, the duo was simply "guilty of a damn good time."
