The 8 PM concert served as a benefit for Ars Nova's summer concert series, the 54/10 Music Marathon, which runs through July 24 and promotes the music of up-and-coming bands.
Fellow American Idiot cast members Brian Charles Johnson and Chase Peacock, who comprise the band Fran Sancisco, opened for Gallagher while Theo Stockman followed the concert spinning as DJ Theocracy.
