The Large Jazz Ensembles are open to all university students. Auditions for the Jazz Ensembles are held during the first three days of the fall and spring semesters. The instrumentation includes saxophones, trumpets, trombones, piano, guitar, bass guitar, drum set and percussion. Since 1990, Jazz Ensemble I has performed in concerts and master classes with a number of internationally acclaimed jazz artists, including drummers Peter Erskine, Steve Smith, Ruben Alvarez, and Ed Soph, trumpeter Wynton Marsalis, xylophonist Ian Finkel, trombonist Slide Hampton, and trumpeter Jimmy Owens. Jazz Ensemble I has experienced a considerable amount of success, including being named "Best College Big Band" at the Eau Claire Jazz Festival in 1993.
