Five-time Grammy-nominated composer-percussionist Akiho returns to Ann Arbor with his steelpan instrument and with Brooklyn-based quartet Sandbox Percussion, a group he’s been collaborating with since 2011. Tonight’s program focuses on works by Akiho, with excerpts from his Pulitzer Prize–winning Seven Pillars, which the New York Times called a “lush, brooding, celebration of noise.” Also, the group performs excerpts from Akiho’s new large-scale piece, Pentalateral, as well as other of his works. 4 p.m., Rackham Auditorium. $32–$58 (students, $15–$20) in advance only at (734) 764–2538 &  tickets.ums.org.
