Born out of Northern California’s chaotic, late-1960s musical stew, The Doobie Brothers’ rugged, real and authentic approach to rock and roll made them biker bar stalwarts. But their self-titled debut album in ’71 went beyond just leather and motorcycles, revealing even more musical layers; sweet three-part harmonies and rootsy, introspective, acoustic flavors.  The Doobie Brothers’ legacy has been built upon not just hit records, but also an unrivaled commitment to musical integrity and a steadfast allegiance to their enthusiastic fan base. The bands ability to evolve in a constantly changing industry and connections to generations of listening audiences is a testament to their craft.  It all began in 1969, when a drummer named John Hartman arrived in Northern California. He was there to meet Skip Spence from the band Moby Grape and become part of a supposed band reunion that never quite got off the ground. But it wasn’t all for naught. Spence (who had also played in the Jefferson Airplane) introduced Hartman to his friend Tom Johnston, a local singer/songwriter/guitarist -and they connected. Hartman and Johnston began playing local Bay Area bars. They soon met singer/guitarist Pat Simmons, whose finger-style playing richly complimented Johnston’s R&B strumming-style, and the foundation for The Doobie Brothers was set.  While their debut album in 1971 did not chart, just a year a later, their second record, Toulouse Street, became a breakout sensation. Producer Ted Templeman helped the band craft a sound that was organic, yet radio friendly, and brought in Little Feat keyboardist Bill Payne to add unique musical textures.
