In his Pierre Boulez Saal solo debut, Indian-­American pianist Kunal Lahiry—who performed a fascinating song recital with Fleur Barron last season—embarks on a journey of musical self-­discovery that leaves behind traditional interpretations of the classical piano repertoire. From the relentlessly revolving staircase of Ligeti’s L’Escalier du diable as a symbol of patriarchal structures to the fugue from Beethoven’s penultimate piano sonata as an expression of queer liberation, Lahiry explores music by a wide range of composers in a highly personal and immersive program that speaks to today’s urgent need for a paradigm shift.
