Okay, I'm not sure why the picture is of Christmas In the Heart, but this recommendation is for the man himself. I first heard Bob Dylan when I was 15 and never looked back. The poetry, the voice that let you know he was really feeling the stories he sang, the dripping venom in the kiss-off songs, the silly wordplay. Easily the greatest musician of the 20th century.
If "Positively 4th St." is not the best bad-ex-girlfriend song ever...I don't know what is. And "Sara" is one of the best great-ex-gf tunes. Cons: If you go to his show to see him perform "just like on the record" you will be disappointed. Go instead to see the man who wrote the songs interpret them as he sees fit.
