Ansonia Quartet

Byungchan Lee, Sumire Hirotsuru, Isabel Kwon, Jocelin Pan


The Ansonia Quartet is embarking on its fourth season together as an ensemble. So far this season, they have held a summer residency at Avaloch Farm Music Institute and performed recitals at Shandelee Music Festival and Robbie Collomore Series.

The Ansonia’s international career was launched off the heels of a successful crowdfunding campaign in 2017. They met their target goal of $10,000 in nine days to tour to Japan where they performed recitals in Oita and Tokyo, and held workshops for Japanese students.

Since then, the quartet has travelled to Nova Scotia for a residency at the Lunenburg Academy of Music Performance, to Toronto for recitals and community engagement performances, and to Durham where they coached and led the Durham Youth Orchestra in a featured joint concert. In the United States, the quartet has appeared at the Chamber Music Society at Lincoln Center for masterclass with Ani Kavafian, performed Elgar’s Introduction and Allegro with the Juilliard Chamber Orchestra, and presented recitals at the Harvard Club of New York, Nicholas Roerich Museum and SOPAC (South Orange Performing Arts Center), Japanese Ambassador’s Residence in Washington D.C.

The Ansonia’s passion to push string quartet boundaries has led to not just a global reach but to fresh literature. They have given world premieres at Juilliard’s 2018 Focus! Festival, MoMA’s Summergarden series, and the New York Choreographic Institute where they also collaborated with dancers from New York City Ballet. The quartet has also infused Argentine tango into their repertoire and collaborated with Grammy-award winning bandoneon player, Hector del Curto.

Formed at The Juilliard School in September 2016, they were awarded a Gluck Community Service Fellowship through The Juilliard School to pursue community engagement endeavors, as well as a coveted position in the Honors Chamber Music Program for the 2017/2018 season. The quartet worked primarily with Ronald Copes and Roger Tapping of the Juilliard String Quartet, as well as with Sylvia Rosenberg and the Dover String Quartet.

ジュリアード音楽院の同級生4人で結成したアンソニア・カルテットは、2017年度の室内楽プログラムの選抜グループに抜擢され、同年夏にはクラウドファンディングで1万ドルの資金を集め、初の日本ツアーを敢行。トロントツアー、リンカーンセンターAlice Tully HallやChamber Music Societyでの演奏、ニューヨークシティバレエとの共演の他、2018年にはニューヨーク・MoMA近代美術館のサマーガーデン・シリーズで、世界初演2曲を含む現代曲4曲を演奏。NYを中心に活動中です。
