I'm very pleased some members are interested to know more about Walter Zimmermann's music. As well as the discs Richard mentions, there is also a disc on Wergo of his stage works
Singbarer Rest and
Die Blinden (this Maeterlinck text has also been set by Beat Furrer). As mentioned, I have recorded his piano works (up to 1998); I feel
Wüstenwanderung is the finest of these. It has also been recorded by Daniel Seel (on a recital disc on Hat Art) and Hermann Kretzchmar (on one of the Mode discs), and has been taken up by other pianists including Philip Thomas and Heather O'Donnell. His longest piano work
Beginner's Mind is on my discs, and also on an old LP by Herbert Henck - an excellent performance (pianistically, at least - without making any claims for my own singing (quite out of tune), I think the intonation there holds its own against Henck's

Walter's other string quartet,
Festina Lente, is recorded on the Arditti's 'For Germany' disc (which also contains Mathias Spahlinger's fantastic quartet
Apo do). This work is known colloquially amngst the quartet as 'The Rack', because of the agonising unisons they have to maintain for long stretches of time.
