Under the leadership of Noe Marmolejo, the Jazz Orchestra is the big band for the Moores School of Music. In addition to performing two concerts per semester at the school, the band regularly appears outside of the school for music festivals, community outreach, and events with Houston performance societies such as DaCamera and Miller Outdoor Theater.

The Jazz Orchestra has also performed at the Texas Music Educators Convention, the Katy Jazz Festival, the Colorado Music Educators Convention, the Texas Jazz Festival (Corpus Christi), and the University of Northern Colorado Jazz Festival.
