The two-time defending Class 3A state jazz champions are seeking a third top honor in a row and the school’s 20th first place trophy at the Iowa Jazz Championships Tuesday. Pella Jazz I will compete among 14 other 3A bands, with the Dutch performing at 2:15 p.m. at the Scheman Building at Iowa State University in Ames. Pella has placed in the top four of the showcase of Iowa’s best high school jazz bands for 38 consecutive years. If the band places in the top two during the day competition, they will perform in a showdown later Tuesday evening.
