Los Lobos and Steve Earle played The Paramount in Huntington, NY, last night, and Dark Star Orchestra guitarist Jeff Mattson joined Los Lobos for a couple tunes during their set.

Also during Los Lobos’ portion of the show, which featured a cover of Traffic’s “Light Up or Leave Me Alone” along with their own cuts like “Gates of Gold,” “Cumbia Raza” and “Emily,” the band welcomed out Chris Masterson and Eleanor Whitmore, also known as The Mastersons, who play with Earle and The Dukes. The couple joined the band for two songs, “One Time One Night” and “Will the Wolf Survive?” Mattson later emerged for the band’s final two songs, a cover of the Grateful Dead’s “West L.A. Fadeaway” and Los Lobos’ “Don’t Worry Baby.”

Watch Los Lobos play Traffic’s “Light Up or Leave Me Alone” below. The band plays the Criterion Theatre in Bar Harbor, ME, tonight.
