Portland’s Third Angle New Music will debut a new commissioned piece at its upcoming show on April 16 at OMSI’s Kendall Planetarium. The composition, called “Spheres,” was written for percussion quartet and three American Sign Language performers. Deaf and hard of hearing audience members can experience the program through haptic vests that translate the sound from the instruments music into physical vibrations. The vests were developed by local nonprofit CymaSpace, which aims to make arts and culture performances accessible to Portlanders who are deaf or hard of hearing.

Sarah Tiedemann is the artistic director of Third Angle. She joins us to talk about the new show and accessibility in the arts.
