Deemed "superheroes of the new music world" (Boston Globe), the JACK Quartet is "the go-to quartet for contemporary music, tying impeccable musicianship to intellectual ferocity and a take-no-prisoners sense of commitment." (Washington Post) "They are a musical vehicle of choice to the next great composers who walk among us." (Toronto Star)

The recipient of Lincoln Center's Martin E. Segal Award, New Music USA's Trailblazer Award, and the CMA/ASCAP Award for Adventurous Programming, JACK has performed to critical acclaim at Carnegie Hall (USA), Lincoln Center (USA), Miller Theatre (USA), Wigmore Hall (United Kingdom), Muziekgebouw aan 't IJ (Netherlands), IRCAM (France), Kölner Philharmonie (Germany), the Lucerne Festival (Switzerland), La Biennale di Venezia (Italy), Suntory Hall (Japan), Bali Arts Festival (Indonesia), Festival Internacional Cervatino (Mexico), and Teatro Colón (Argentina).

Comprising violinists Christopher Otto and Austin Wulliman, violist John Pickford Richards, and cellist Jay Campbell, JACK is focused on new work, leading them to collaborate with composers John Luther Adams, Chaya Czernowin, Simon Steen-Andersen, Caroline Shaw, Helmut Lachenmann, Steve Reich, Matthias Pintscher, and John Zorn. Upcoming and recent premieres include works by Derek Bermel, Cenk Ergün, Roger Reynolds, Toby Twining, and Georg Friedrich Haas.

JACK operates as a nonprofit organization dedicated to the performance, commissioning, and spread of new string quartet music. Dedicated to education, the quartet spends two weeks each summer teaching at New Music on the Point, a contemporary chamber music festival in Vermont for young performers and composers. JACK has long-standing relationships with the University of Iowa String Quartet Residency Program, where they teach and collaborate with students each fall, and the Boston University Center for New Music, where they visit each semester. Additionally, the quartet makes regular visits to schools including Columbia University, Harvard University, New York University, Princeton University, Stanford University, and the University of Washington.
