On May 10, 1965 (14 months before I was born), Dylan performed the final solo acoustic concert of his career at London's Royal Albert Hall. Two months later, he famously "went electric" at the Newport Folk Festival - and the music world was never the same.
Fans had to suspect change was coming during that 1965 tour - Dylan's recently released fifth album, "Bringing It All Back Home," featured the first electric songs of his career - but nobody could have predicted the outcry that accompanied his subsequent full-band live performances.
Dylan continued to play solo acoustic sets on his 1966 world tour, but those shows are legendary for the controversial electric sets he performed with the musicians who would later be known as The Band. The frenzied, amped-up, somewhat-sloppy electric portions of those shows focused on new material from "Highway 61 Revisited" and "Blonde on Blonde," but also featured dramatically reworked versions of his older songs ("it used to sound like that; now it sounds like this," is how Dylan coyly introduced 1964's "I Don't Believe You" on the live album from that tour) that proved wildly divisive and alienated much of his folk music audience.
Careers have ended over far less radical creative departures. Dylan's, obviously, didn't - even if he didn't tour again for another eight years.
We bring this up now because Dylan turns 70 two weeks from today, and it's not too early to begin celebrating the legacy of one of the most influential musicians of the past 50 years.
Maybe the most influential, at least from a songwriting perspective.
The fact that he's still touring, still making quality music (2009's "Together Through Life" has a handful of standout songs, if you can tolerate what's left of his road-ravaged voice) means that celebrating Dylan's milestone birthday is more than just a nostalgia trip.
At (nearly) 70, Dylan is not a museum piece, but a still-viable artist. And that, 50 years after first making his mark on the New York City folk scene, is a remarkable achievement.
AARP The Magazine honors Dylan on his birthday with tributes from dozens of his contemporaries. A few samples:
n "Bob is ageless because he keeps turning new corners, beating down new paths, redefining himself and his art as he goes" - Martin Scorsese
n "Bob dragged us from literary immaturity and made us grow up emotionally. He dragged us into the world of alliteration and metaphor in a way that nobody else could do. He was our higher education." - Judy Collins
n "Bob tells it like he feels it, and he's been like that for his entire career." - Smokey Robinson
n "I'm gonna want to hear what Dylan has to say as long as he wants to say it." - Bob Weir
But obviously, it's not just celebrities who have been affected by Dylan and his music.
I got into Dylan's music relatively late. As a teen, I owned "Bob Dylan's Greatest Hits" on vinyl and - I'm embarrassed to say - nothing else. A college roommate owned "Blood on the Tracks" on CD and I spent many an inebriated night with that album, but it wasn't until 2001 that I seriously began adding Dylan albums to my music collection.
I've been obsessed ever since.
"Highway 61 Revisited" is among my all-time favorite albums by anyone, and that album's opus "Desolation Row" is probably my favorite Dylan song, but I find joy in almost all eras of his career (save, perhaps for the mid-'80s).
