Jasper String QuartetWinner of the prestigious CMA Cleveland Quartet Award, Philadelphia's Jasper String Quartet is the Professional Quartet in Residence at Temple University's Center for Gifted Young Musicians and the 2017-18 Guest Artist in Residence at Swarthmore College.

The Jaspers have been hailed as “sonically delightful and expressively compelling” (The Strad) and the New York Times named their latest album, Unbound, as one of the 25 Best Classical Recordings of 2017.

"The Jaspers... match their sounds perfectly, as if each swelling chord were coming out of a single, impossibly well-tuned organ, instead of four distinct instruments." (New Haven Advocate)

Current Projects
The Quartet launched their inaugural season of Jasper Chamber Concerts in 2016-17, a series in Philadelphia devoted to world class performances of masterworks from around the world and Philadelphia. The Quartet continues with the second season in 2017-18.

The Jasper String Quartet also looks forward to their 2019 commission of Lera Auerbach, Akira Nishimura, Chris Theofanidis and Joan Tower for 4 Seasons | 4 composers, a work bringing the brilliant muse of the seasons to the string quartet genre.

The Quartet completed their latest commission tour of Aaron Jay Kernis’ 3rd String Quartet "River" in 2017 at Wigmore Hall and their Carnegie Hall Recital with the work received a glowing review in The Strad.

The Jasper String Quartet's next album on Sono Luminus will feature Kernis Quartet No. 3 and Debussy Quartet. This, their 5th album, completes the Kernis Quartet Cycle and adds to their recordings of Beethoven Op. 59, No. 3, Beethoven Op. 131 and Schubert Death and the Maiden. Their 2017 album, Unbound, features the first recordings of quartets by Donnacha Dennehy, Annie Gosfield, Judd Greenstein, Ted Hearne, David Lang, Missy Mazzoli and Caroline Shaw.

Community Engagement
The Quartet has performed hundreds of outreach programs in schools and enjoys educational work of all types. In 2018, the Quartet received their second Picasso Project Grant from Public Citizens for Children and Youth. This grant supports the Quartet's work with a South Philadelphia Public Elementary throughout the spring, culminating in a performance together.

In addition, Fischoff National Chamber Music Association recognized the Quartet's "outstanding and imaginative programming for children and youth in the United States" with their 2016 Educator Award.

Our History
In 2008, the Jaspers swept through the competition circuit, winning the Grand Prize and the Audience Prize in the Plowman Chamber Music Competition, the Grand Prize at the Coleman Competition, First Prize at Chamber Music Yellow Springs, and the Silver Medal at the 2008 and 2009 Fischoff Chamber Music Competitions. They were also the first ensemble honored with Yale School of Music’s Horatio Parker Memorial Prize, an award established in 1945 and selected by the faculty for “best fulfilling… lofty musical ideals." In 2010, they joined the roster of Astral Artists after winning their national auditions.

The Quartet was the 2010-12 Ensemble-in-Residence at Oberlin Conservatory and, in conjunction with Astral Artists, was awarded a 2012 Chamber Music America grant through its Residency Partnership Program for work in Philadelphia schools. From 2009-2011, the Jaspers were the Ernst C. Stiefel String Quartet-in-Residence at the Caramoor Center for Music and Arts (Katonah, NY). They were the first ensemble to be invited for a second year as such.

Our Philosophy
The Jaspers perform pieces emotionally significant to its members ranging from Haydn and Beethoven through Berg, Ligeti, and living composers. They have commissioned string quartets from some of today’s best composers, including Aaron Jay Kernis, Andrew Norman, Nicholas Omiccioli, Conrad Tao and Annie Gosfield. Critics and audiences commend the Jasper String Quartet’s “programming savvy” ( and they have performed throughout the United States and in Canada, England, Italy, Japan, Korea, Norway and Panama.

JSQ Origin
Formed at Oberlin Conservatory, the Jaspers began pursuing a professional career in 2006 while studying with James Dunham, Norman Fischer, and Kenneth Goldsmith as Rice University’s Graduate Quartet-in-Residence. In 2008, the quartet continued its training with the Tokyo String Quartet as Yale University's Graduate Quartet-in-Residence.

The Jasper String Quartet is named after Jasper National Park in Alberta, Canada and is represented exclusively by Dispeker Artists. For more information, please visit:
