Trombone benchmark pieces

i'm looking for a relatively challanging trombone piece to play for my end of year concert next year... i'm studying for my grade 8 trinity college exams (as an indicator of my skill level) I am currently tackling "Morceau Syphonique" by Guilmant and The David trombone concerto. But i also like to play jazz pieces... Maybe somebody out there has a suggestion for a piece i can play...something that i should be able to perfect in a year... (yeah, it's a long time)

well thanks i guess.... :)

Flight of the Bumblebee. :)

hehehehehheeee. is it possible....? i guess it must be. maybe lindberg.

Lindberg has indeed played it, yes. Quite exceptionally, might I add.

There is a wonderful Concerto for trombone by G.C.Wagenseil - it isn't very hard. Practically one of the most beautiful trombone concertos in history.
