I stumbled apon this site completely by accident when looking for the lead sheet of a great tune called Descarga Khanalonious by guitarist Steve Kahn. Firstly I was pleasantly surpirsed to find it on his website, but even better was that the website has a huge section dedicated to both transcriptions and analysys by Steve himself, as well as a section dedicated to Steve's own lead sheets and compositions. Compositions are also presented with a corresponding sound clip, and an analysis. Check out Kahn's Korner 1 and 2 for a veritable goldmine of great stuff to study.
