This recording features the Bugallo-Williams Duo playing György Kurtág's complete works for piano duet and two pianos as included in the eight published volumes of Játékok (Games). The work's original concept was as a collection of pedagogical performance pieces, and the composer has been adding to the series since 1973. Eight volumes had been published as of 2010, and volumes IV and VIII are for piano 4-hands or two pianos. In addition to a focus on rhythm and time, Kurtág also addresses techniques including using palms, fists and forearms as a means of exploring the keyboard.
