This collection was conceived as a tool to help the trombone section refine their skills as a unit of the contemporary big band, including balance, blend, articulation and phrasing. It includes 6 full performance pieces in a variety of styles. Optional rhythm section parts are included, along with written or ad lib solos for any player. Two downloadable MP3 tracks are included for each piece: a full performance with rhythm section, and a rhythm section only MP3 that can be used in rehearsals or performances without a rhythm section.
