What is an artist? At the end of day, it's someone who makes art. That's the only good definition I've ever heard. Someone like, say, BOB DYLAN, who turns 75 today. At an age when many of his colleagues have semi-retired, or perhaps are going through the motions (and the commerce), DYLAN continues to do exactly what he's always done: write songs, make records, get on buses (or maybe cars or planes, I don't know, I'm not stalking him), play shows, rinse, repeat. And paint sometimes. He has lived, it would seem, an exemplary artist's life, always working, always moving, and seemingly always getting grief for it. He stopped writing folk songs. He went electric. He disappeared. He went Christian. For the 38th time in a row he made an album that isn't "BLOOD ON THE TRACKS." He mumbles. He doesn't play the hits. Or maybe he does but no one recognizes them. Or maybe they're FRANK SINATRA's hits. Or maybe people could stop trying to second-guess and just listen. While he's still here. In a year in which we've lost a few too many transformational musicians, let's celebrate those who are still transforming and still making their art. DYLAN acoustic. DYLAN electric. DYLAN as 1965's KANYE WEST. DYLAN and JOHNNY CASH. DYLAN with the PLUGZ. DYLAN performing for a single fan in PHILADELPHIA in 2014. My favorite DYLAN song, if you ask me at this exact moment.
