"Thank you for your enquiry about music held at Heritage Quay. I can confirm that we hold a score for Timothy Moore's concerto for clarinet and strings (BMC/SC/64174). It appears that the movement titles correspond with the recording link you provided: I Allegro (listed in the score as 5.5 minutes), II Adagio (listed as 3 minutes) and III Rondo: Allegro (listed as 5 ¾ minutes). From a brief listen, the opening bars do seem to correspond too.

I am not sure if I will take it any further as it was more a matter of curiosity than anything else and it seems to me that this "Myaskovsky" concerto is highly likely a hitherto unrecorded concerto by Timothy Moore.
