Before the start of morning classes during the Atlantic Brass Quintet Summer Seminar, Jobey Wilson (right), a member of the Triton Brass Quintet and the low brass instructor for the Boston College Marching Band, practices beside a fountain near the O’Neill Library with Patrick Bigsby (rear), an undergraduate at the University of Iowa. The two-week seminar, copresented by the Boston College Bands program, includes coaching sessions, master classes, and recitals. Members of the two quintets and Sebastian Bonaiuto, director of bands, instruct some 50 visiting students from the U.S., Canada, and Japan.
