By 1966, Donovan had evolved beyond his initial folk troubadour style and fully embraced the budding "flower power" movement. Finding inspiration in jazz, blues, world music and West Coast U.S. rock, he partnered with top UK producer Mickie Most and arranger John Cameron to capture the sound he was pursuing in his mind. Their first collaboration, the "Sunshine Superman" single, was a smashing success, reaching No. 1 on the U.S. charts and establishing Donovan as a major pop star. Today, Donovan is widely regarded as one of the most influential songwriters and recording artists. During his induction into the Rock and Roll Hall of Fame in 2012, it was stated that he, "singlehandedly initiated the Psychedelic Revolution with his album Sunshine Superman.” To celebrate the 50th anniversary of his landmark 1966 album, Donovan launched a North American tour featuring sold-out shows in New York, San Francisco, Seattle, and Toronto. The GRAMMY Museum welcomed Donovan to its Clive Davis Theater in 2016 for an intimate discussion and special performance of his classic hits.
