A devoted advocate of new music, Mr. Calloway has performed with leading ensembles on both coasts and with the New Juilliard Ensemble both in New York and abroad, in addition to frequent appearances on Philadelphia’s ‘Bowerbird’ series. Among the hundreds of premieres he has presented are solo and ensemble works of Berio, Knussen, Lachenmann, and Pintscher and he has collaborated intensively with some of today's most important composers including Birtwistle, Carter, Davidovsky, Dusapin, Henze, Hosokawa, Husa, Franke, and Rihm. As a dedicated supporter of young composers, he presented last season a series of concerts and seminars at Harvard and Temple universities of solo cello works newly composed for him, a project he repeats this spring both across the U.S. and abroad, and returned last summer to Spoleto USA where he gave the public premiere of Yanov-Yanovsky’s 'Hearing Solutions' for cello and ensemble.

Mr. Calloway prizes his work with Pierre Boulez and the Ensemble InterContemporain, both at the Lucerne Festival and just this summer at the Zug (Switzerland) Kunsthaus in Schoenberg's 'Serenade' as part of a major Kandinsky/Gerstl exhibit, in addition to his 1collaborations with the violinist Gilles Apap; with tap dancer Savion Glover; and with Eduard Schmieder and iPalpiti. He is also artistic director of X-band, a newly formed ensemble based in Boston. A native of Philadelphia, Jason Calloway is a recent graduate of the Juilliard School and the University of Southern California. His teachers have included Ronald Leonard, Rohan de Saram, Lynn Harrell, Fred Sherry, Orlando Cole, Robert Cafaro, Joel Sachs, Felix Galimir, Luis Biava, and Seymour Lipkin. Mr. Calloway is grateful for the assistance of the Maestro Foundation.
