One of the great classics of 20th century choral modernism. Ligeti's thrilling 'Lux Aeterna' achieved global fame following its use on the soundtrack to Stanley Kubrick's 1968 film '2001: A Space Odyssey'. For 16-part Choir SATB, the work deploys Ligeti's technique of micropolyphony and uses cluster chords to create a densely buzzing haze of sound. Vocal Score.
