You can never be sure what Bob Dylan is going to do when he goes on stage to perform, or when he releases a new album. The one thing you can be sure of is that he will do whatever he wants to do, without worrying much (if at all) at how it will be received. It isn't just since he became an elder statesman (he turned 71 this year) that Dylan has done his own thing. He's done it for the most of the 50 years since he released his first album. He's doing it again with his 35th album, Tempest, which was released on Tuesday (9/11) and which has a typically Dylanian twist on life, but from a different perspective than when he was, well, not a senior citizen.
