About Us
Secondary Dominance is ISU's premier all-treble a cappella group. Since established in 2004, SD has been delighting audiences with their instrument-free performances on campus and around the Bloomington-Normal community. We perform a range of music - anything from pop to R&B to Broadway - and we arrange the majority of it ourselves! Our mission is to produce beautiful music while pushing the boundaries of all-treble a cappella. Secondary Dominance is a student-run Registered Student Organization with Doctor Mark Grizzard acting as faculty advisor. If you are interested in booking Secondary Dominance to sing at your event, please e-mail our group email [email protected] or our current President, Olivia Earll, at [email protected]!
