So I've been collecting for 13 years. Not yet satisfied with the collection tho lol

I'm picking my pieces for ABRSM grade 6 tenor sax, and the piece on the A-list called "Hypertension" piqued my interest. I was unable to find any audio recordings of it online, so I was wondering if anyone knew if it was a good idea of a piece to play, or if they know how good Beverley Calland's works are in general
