Tedeschi Trucks Band’s Wheels of Soul tour continued last night at the Wolf Trap in Vienna, VA as the TTB headlined the event with a 15-song set that featured numerous covers and a sit-in from members of Los Lobos.

About halfway through the band’s set, following a take on the Beatles’ “Within You Without You” and their own “Just As Strange,” the large ensemble got larger by welcoming out Los Lobos members David Hidalgo and Steve Berlin for a take on the Allman Brothers’ “Don’t Keep Me Wonderin’.” Watch that performance below.

Additionally, the group mixed in ZZ Top’s “Goin’ Down to Mexico” as well as George Jones’ “Color of the Blues” and a closing number of Joe Cocker’s “The Letter,” which has become a mainstay for the group.
