Ten pianists from across the musical world—including Timo Andres, Aaron Diehl, Daniela Liebman, and Jason Moran—come together for a marathon performance of Philip Glass’ complete Piano Etudes during the composer’s 90th-birthday year. Longtime Glass interpreters and special guests each bring a distinct perspective to this unusually personal body of work.

Across 20 etudes, whirling arpeggios, abrupt rhythmic and harmonic turns, and meditative discipline form a musical self-portrait of Glass’ evolving practice. Heard complete, the cycle reveals both the intimacy and inventive range of a composer whose language has reshaped contemporary music. Philip Glass will not be present.
