This piece was the second trombone quartet I composed, and it was written by request of a good friend and bass trombonist, Lucas Kaspar. The piece is presented in three movements, and is very challenging in all aspects. The first movement is brief and aggressive, setting up the motives and themes that will continue to show up throughout the piece. The second movement is a bass trombone solo and the longest of the three movements, challenging the bass trombonist in all aspects of playing. The third movement is very playful and rhythmic, and draws away from the intensity of the other two movements, bringing the whole quartet to a surprisingly comfortable end.
