“67th Annual Study Break Concert”: U-M Friars.
This self-styled “crack squad of ‘supercrooners,’” an a cappella octet drawn from the Men’s Glee Club, performs an eclectic mix of everything from slow ballads to upbeat dance tunes to original parodies that give a collegiate twist to classic songs. 8 p.m., Rackham Auditorium. Tickets $12 in advance at the Michigan Union Ticket Office (muto.umich.edu), and (if available) at the door. firstname.lastname@example.org.
