Invite a trombonist to join your flute choir! Henry Fillmore's Lassus Trombone for SOLO trombone (or contrabass flute) was arranged for a concert that featured a trombone soloist with the Nashua (NH) Flute Choir. The instruments blend well and the combination brought in a wider audience than usual. Lassus is the most famous of Fillmore's trombone smears - pieces that feature long glissandos for the trombone. Can't find a trombonist? A contrabass flute part is included, just in case! It is scored...
