Grammy award-winning singer, songwriters Michael McDonald and Boz Scaggs team up for a co-headling tour at the Vina Robles Amphitheatre on August 16.

With a career that encompasses five Grammys, numerous chart successes, personal and professional accolades, as well as collaborations with some of the world’s most prominent artists, Michael McDonald remains an enduring force in popular music.

His distinctive and soulful voice is easily recognizable and is one of the most yearningly emotive instruments of our times. To this add formidable songwriting and keyboard skills, and you have an artist who has been a singular musical presence for four decades. From ‘70s-era Doobie Brothers classics including Top 40 singles as “Takin’ It to The Streets,” “It Keeps You Runnin’,” “Minute By Minute” and “What A Fool Believes,” to his solo hits like “I Keep Forgettin’” through two highly-acclaimed Motown albums, genre-busting guest spots and innovative concept shows, the five-time Grammy Award winning McDonald is both timeless and ever-evolving.

His distinct vocal style also made him one of the world’s most sought-after session singers. Beyond his hits with The Doobies, McDonald has lent his voice to records by an A-Z of artists, including Ray Charles, Aretha Franklin, Elton John, Joni Mitchell, Vince Gill and Grizzly Bear. During the ‘80s and ‘90s, his solo career zoomed from success to success on the wings of evergreen hits like “Sweet Freedom,” “On My Own” (a duet with Patti LaBelle) and the Grammy-winning duet with James Ingram “Yah Mo B There.”
