The voice that launched a thousand yacht rock revues has lost some of the range that made it the favored instrument of everyone from Christopher Cross to Steely Dan. But even with those otherworldly high notes out of his reach, Michael McDonald is one of the quintessential comforts of pop. Last year, the former Doobie Brother released his first original material solo album in more than 16 years, the introspective Wide Open, but you know you’re coming to hear him “keep the spirit alive” on such chestnuts as “Sweet Freedom” and “On My Own.” And what better opening act than Peter Cetera, the former Chicago singer and bass player whose distinctive tenor was as much a part of the ’70s as McDonald’s soothing baritone. Come hear this summit of two yacht rock giants. Read more>>> Michael McDonald performs with Peter Cetera at 8 p.m. at the Filene Center at Wolf Trap, 1551 Trap Road, Vienna. $35–$80.
