Solos are in the guitar and tenor 2. This piece heavily relies on guitar on the opening melody. The technique that Ben Monder used to bend notes is exceedingly difficult. One alternative could be playing lap steel guitar, or alternatively, not bending the notes at all of course.
5 reeds, 4 trumpets/flügelhorns, 3 trombones, 1 bass trombone, accordion (this piece can be played without accordion), guitar (consider lap steel as a great alternative), piano, bass (with bow on intro), drums
