I've never really liked Bob Dylan. His songs are fabulous, as long as somebody else sings them. There are a few exceptions, of course, I do like Lay Lady Lay.
Anyway, I just listened to Maria Muldaur's Heart Of Mine - Love Songs Of Bob Dylan. It was ok, not sure if I'd recommend it though.
I am currently listening to Joan Baez's Vanguard Sessions: Baez Sings Dylan. She, of course, has a beautiful crystal clear voice.
