The Catalyst Quartet “Invariably energetic and finely burnished…playing with earthy vigor.”  - The New York Times Touring April / May 2012; general availability 2012-2013

Hailed by the New York Times at their Carnegie Hall debut as “invariably energetic and finely burnished…playing with earthy vigor,” the Catalyst Quartet is comprised of top Laureates and alumni of the internationally acclaimed Sphinx Competition for young Black and Latino string players. The mission of the ensemble is to advance diversity in classical music and inspire new and young audiences with dynamic performances of cutting-edge repertoire by a wide range of composers. Founded by the Sphinx Organization, the Catalyst Quartet combines a serious commitment to diversity and education with a passion for accessible contemporary works.

The quartet has held residencies both domestically and abroad, and serves as principal faculty at the Sphinx Performance Academy at Oberlin College and Roosevelt University in Chicago. The Catalyst Quartet members are also visiting teaching artists at the Sphinx Preparatory Music Institute, hosted by the Detroit Symphony Orchestra.

Having been featured in The Strad and Strings magazines, as well as on Detroit Public Radio, with recordings to be released later this year on the White Pine label, The Catalyst Quartet maintains an active performing schedule and will be leading the Sphinx Virtuosi on their national tour in the fall of 2011, which includes a return to Carnegie Hall on October 12.
Inspired by music’s ability to transform, the Catalyst Quartet seeks to change the way that classical music is perceived through diverse programming for a wide range of audiences.
