How did Bryan Adams begin his music career?

Bryan Adams taught himself to play guitar, and at age 16 he left high school to pursue music full-time, becoming the lead vocalist for the glam-rock band Sweeney Todd. He worked in a recording studio, toured, and recorded for Sweeney Todd’s album If Wishes Were Horses (1977). Soon after the album’s release, he met Jim Vallance, who recognized Adams’s talent but suggested further vocal training. With Vallance’s help, Adams developed a powerful, distinct sound, comparable to Rod Stewart, Paul Rodgers, and Steve Marriott. In 1980 Adams released his first self-titled album and embarked on a four-month Canadian tour.
