We haven't heard a better original Latin tune at this grade level than Pollo Roja! It's a cha-cha to be performed at around 146 bpm, has easy brass ranges, includes a written or ad lib alto sax solo, a cool melody, section solis, and it's fun to hear and play.  This is a well-crafted chart that will guarantee maximum interest from players and audiences! Playable with optional reduced or expanded instrumentations. Highly recommended!
