Matthew - if you are looking for something slightly more "mainstream" and Russian, you might want to check out
Russian Roulette by Paul Archibald - a book of arrangements for trumpet and piano, published by Brass Wind Publications (
http://www.brasswindpublications.co.uk/) which includes:
Capriccio Espagnol (Rimsky-Korsakov)
Ballet Suite (Tchaikovsky)
Prelude 18 (Shostakovich)
All of which I think would suit your requirements.
Back to the original idea - my aims for the restarting of school.
To keep my students motivated.
To work on my own techniqiue (somethinng that frequently gets forgotten during the teaching time)
I am aiming NOT to get too frustrated with a teaching service that is more interested in money than quality of teaching.
