Trying to get good continued

So, to begin the process of getting good again, I dug out the Arban and Rochut, and bought a copy of the Gordon Jacob trombone concerto. Might try to put together a recital; thinking Barat’s Andante et Allegro, the Halsey Stevens Sonatina, a Vivaldi sonata, the Jacob (maybe not all three movements) and perhaps something like Elegy for Mippy II or a jazz thing to close.

Trombonists – any other lit suggestions/substitutions?
