Tedeschi Trucks Band and Lukas Nelson perform a co-billed concert at the Greek Theatre in Berkeley, presenting a mix of blues-rock, soul, and roots-infused country-rock. The show pairs the ensemble-driven, improvisational sound led by Susan Tedeschi and Derek Trucks with Lukas Nelson’s singer-songwriter, Americana-tinged repertoire, promising extended jams and virtuosic guitar work. The performance takes place in the historic open-air amphitheater on the UC Berkeley hillside, a longtime venue for large-scale live music events.
