TOULOUSE STREETThe Doobie Brothers shuffled personnel a bit after their debut album, changing bass players and adding a second drummer. For whatever reason, this sophomore effort was the one that kicked off their long streak as one of the most popular bands in America. The basic sound of TOULOUSE STREET isn't really all that different from the Doobies' previous effort. There's a similar mix of acoustic guitars, gospel harmonies, and overall post hippie mellowness.
