The Zac Brown Band have expanded their lineup for a newly-announced summer tour.

Matt Mangano will join the band as a full-time member for their Great American Road Trip Tour, which kicks off in May in Lincoln, Neb. The bassist has appeared sporadically with the group onstage in the past, and took part in the recording sessions for 'Uncaged' and 'The Grohl Sessions Vol. 1.'

Additionally, longtime ZBB bassist/vocalist John Driskell Hopkins will continue in those roles, but also expand his participation in the group to include guitar, baritone guitar, ukulele, upright bass and banjo.

“We’re always growing as musicians and challenging ourselves to bring new things to our fans," Zac Brown says. "Hop is an amazing talent and I can’t wait for people to see what we’ve got coming for the live show.”

Kacey Musgraves will appear as the opener on four of the upcoming shows.

The tour kicks off May 24, and will run for nearly 30 shows before wrapping up in New York on Aug. 15. See a list of tour dates below.
