Even today, everything about Highway 61 feels like a riddle, this curious musical vessel overstuffed with great songs and wiser-than-thou pearls of boho wisdom. It’s also the rare record that not only succeeded, but excelled in the face of unprecedented controversy. Just months after being publicly assailed for going electric on Bringing It All Back Home, it seemed like Dylan had made his bed. Instead he dove even further into rock and roll only to come out the other side with the best record of his career. That was saying something in 1965, but it says a whole lot more that Highway 61 still earns the title five decades later.
