Seeing Bob Dylan in his twilight years has its ups and downs.

Seeing Bob Dylan in his twilight years has its ups and downs. On the plus side: You're seeing Bob Dylan, legendary folk-rock singer-songwriter and an iconic counterculture figure for more than four decades. On the minus side: Dylan now grumbles his way through melodies that used to soar and has rearranged many of his best-loved works beyond recognition. How does it feel? Depends on your level of devotion and your taste (tolerance?) for old, crotchety Bob (as opposed to young, uppity Bob).
