When experiencing Pierre Boulez’s First Piano Sonata, one should leave all listening habits behind and become a blank page, as the composer himself intended to be—says Pierre-Laurent Aimard, long considered one of the most erudite performers of Boulez’s music. He presents this radically unconventional 1946 work together with George Benjamin’s Shadowlines and a new piece for piano duet, for which he is joined by the composer.
