In 1972, the infectious strumming riff that opened ‘Listen to the Music’ introduced fans to the uniquely American sound of the Doobie Brothers. Their blend of rock and R&B produced a string of hits throughout the next decade. At age 40, ‘Listen to the Music’ remains a classic rock radio staple and the Doobies -- with founding members Tom Johnston and Patrick Simmons -- still maintain a busy tour schedule.
