Singer-songwriter David Crosby ranks among the last musicians standing from the Woodstock generation. A Grammy winner twice inducted into the Rock and Roll Hall of Fame—as co-founder of both the Byrds and Crosby, Stills & Nash—he has been called everything from an asshole (by himself) to an iconoclast, and often serves as a cautionary tale about the dangers of hedonistic excess among the rock star set.

But at 80, the Croz has decidedly mellowed. He’s also entered a new phase in life as an elder statesman enjoying a late-career renaissance. His new album For Free just dropped to glowing reviews, his health is sound in body and mind, and he regularly revels in his role as the nation’s premier joint rolling critic via his always engaging Twitter feed.
