György Ligeti’s choral and orchestral music hit the mainstream when it was featured in the soundtrack of 2001: A Space Odyssey, but his equally remarkable chamber works remain less well known. While indebted to his compatriot Bartók for its folk-inflected passages, Ligeti’s First Quartet, subtitled Métamorphoses nocturnes, is nonetheless a work of striking originality. The Second Quartet, composed around fifteen years later, abounds in contrasts between glacial stillness and manic activity, mechanistic pizzicatos and gentle oscillations. His early Andante and Allegro is richly expressive and easily accessible.
