In 2001, Tess and Melissa met as doctoral students at Michigan State University and decided to collaborate on a recital. Since then, they have collaborated on numerous performances. Both were co-founders of the Mackinac Island Community Foundation Summer Concert Series. This chamber music series has featured the duo for many years, allowing them to experiment with a wide-range of musical styles. After realizing the sonic potential inherent in such an extreme register distribution, they decided to seek more repertoire for the non-traditional pairing. After over a decade of performing in recitals, house concerts, school presentations, and sound healing events, Extreme Duality has acquired a large body of music consisting of arrangements of existing works as well as original compositions dedicated to the duo. Extreme Duality was recently featured on the disc Talking In My Sleep: Chamber Music of Murray Gross released on the Blue Griffin Recording label. In 2014, Tess and Melissa became certified as Music Practitioners through the Music for Healing and Transition Program™.
