Every now and then I read a review of something outside of my normal listening, and the review is so good I want to try it. In this case, it's John Coltrane's One Up One Down. So I read the review on Amazon, and it might not be the best first CD to get from him. There's also the Very Best of John Coltrane, Live at Birdland, or Thelonious Monk Quartet with John Coltrane at Carnegie Hall. Any suggestions? Or if I want to get a couple?
