Michael Drewes : Pieza para el trombón (Piece for Trombone and String Orchestra)

When I wrote this piece it started out for double bass and piano, and later I decided to change it for the trombone. Here, the tenor trombone is shown,this time, accompanied by a string orchestra. For the alternatives for alto and bass trombone, which latter one is indeed the transcription from the original double bass, please refer to the version for trombone and piano.
