Gustav Holst: Duo Concertante for Trombone & Organ (1894) 

The ending is so powerful! Organ accompaniment is something I wish composers would use more; especially in combination with the trombone.

Gustav Holst - a trombone player himself. A man of great talents and seemingly small ego who was almost embarrassed by the success of The Planets. I wish someone would do a quality documentary on him! Also known for choral music - In the Bleak Midwinter.

Interesting piece. Thx for the upload. Shared on Google+

I remember doing this solo back in music school during my jury and recital.
