The Orion String Quartet is a leading U.S. chamber ensemble noted for combining traditional and contemporary repertory and for a variety of collaborative work. Formed in 1987, the four members of the quartet -- Todd and Daniel Phillips, who alternate as first and second violinists, violist Steven Tenenbom, and cellist Timothy Eddy -- are all prominent educators in the New York area. In 1997, the Orion String Quartet released its debut album. Its solo debut followed three years later with an album of works by Dvořák. In 2016, it issued an album of works by Del Tredici.
