They are currently the only string quartet touring multiple quartets by Ben Johnston, which are notoriously  difficult, and were the first group to premiere Johnston's music at the Library of Congress in Washington, D.C in 2016. In 2019, the quartet launched the "Pacific Pythagorean Music Festival", a music festival dedicated to works of just intonation. They were highlighted performers at the Pittsburgh "Beyond 2020: Microtonal Music Festival".
