Art Pepper was one of the most influential alto saxophonists in the 50s and 60s and considered one of the founders of the West Coast Jazz movement. As a Californian, I’m a fan of West Coast Jazz in general and Art Pepper in particular. There was a lightness to his sound that is delightful. Unfortunately, Art had a lifelong heroin problem and, frankly,  a rough life including several prison stints. There is a great documentary about Art Pepper, called Art Pepper: Notes from a Jazz Survivor. Over the Rainbow (iTunes) is a great Art Pepper track because he plays the whole thing solo and really stretches out.
