As of today, it is possible to order the scores of some of Ray's compositions from this site. Go to the (new) 'composing' section from the main menu and you'll find the 'catalog'. There you will find more information on how to order the sheet music and also some rudimentary (for now) samples of the compositions on offer. Currently the catalog features one big band compostion: "On the brink", but more are to follow soon (so you might want to check regularly!), including compositions for other ensembles than big band.
