Bob Dylan: 30th Anniversary Concert at Madison Square Gardens

BOB DYLAN'S SONG catalogue is so varied and vital that Friday's four-hour concert at Madison Square Gardens barely got the key in the door of his musical warehouse. But since Dylan himself has shown such recklessness in rendering his repertory unrecognizable on stage in recent years, the presence of an all-star cast to the Garden to celebrate his 30 years of recording was a smart, successful concept.
