I cannot overstate how timeless Susan Tedeschi’s voice is.

Susan, Derek and the rest of the Tedeschi Trucks Band horns and back-up vocalists joined Los Lobos on stage for a couple of tunes at the end of Los Lobos’ set at Red Rocks last week.

Listen to Susan nail the vocals on Marvin Gaye’s classic song “What’s Going On?”

Thanks to PanicStream for the stream. Listen to the full recording of the show.
