Greensky Bluegrass brought their tour to The Warfield in San Francisco on Friday night for a show that included a collaboration with ALO guitarist Dan Lebowitz, who joined the band for their final two songs of the first set.

Lebo jumped on stage with Greensky for their own “Fixin’ to Ruin” and then a finale cover of Fleetwood Mac’s “The Chain,” which the band has played previously with guests like Nicki Bluhm and others.
