He’s calling it the “Endangered Species Tour.” Rock’n’Roll Hall of Famer Dave Mason has been at it for six decades. He left the groundbreaking British band Traffic before the ‘60s were even over. Author of over 100 songs, with three gold albums, he’s popped up on albums by the Rolling Stones, the Jimi Hendrix Experience, George Harrison and Paul McCartney. He’s collaborated with Stevie Wonder, Michael Jackson, Graham Nash, Stephen Stills and Eric Clapton. He’s got a hot young band behind him and the set list should be a history of rock’n’roll.
