Bastille Musique presents its fortieth release »György Kurtág: Secreta« featuring Quatuor Béla. The album contains a new studio production of Kurtág’s complete works for string quartet from 1959 to 2011, including the first recording of a previously unpublished composition. The recordings, produced by the SWR, are complemented by a 56-page bilingual booklet (EN, DE) with texts by Tobias Bleek, a conversation with the quartet and the recording producer, several autograph pages and two concertina-fold inserts with photos of the composer and the interpreters in the recording studio.
