Guster are taking the summer off while drummer Brian Rosenworcel focuses on his new twins. But the group has confirmed a big Labor Day Weekend show. The organic pop band will co-headline a show with O.A.R. at Park City, UT’s Montage Deer Valley on September 1. For this event, the members of Guster will be backed by the Guster String Players who recently augmented them on their spring acoustic tour. As previously reported, Guster are one of the initial acts confirmed for Port Chester, NY’s recently reopened Capitol Theater.
