Claude Delangle is a true virtuoso in every sense of the word. On this cd he focuses on some abstract, unaccompanied pieces of sax literature. All of which require great finger and throat technique from the performer. He executes this perfecly on all 4 saxophones he plays on this cd. His tone is very pure and even and his intonation, as usual, is dead on. This cd should be in every classical saxophonist's library along with several other Delangle cd's. This guy is only getting better as he progresses.
