There is only one recording of Erich Zeisl's Requiem Ebraico, and it can be ordered from AmazonUK although, be advised that it may take 4-6 weeks for delivery.
Lawrence Foster conducts the Rundfunk Sinfonieorchester und Chor Belin (Decca 460 211-2) and the piece is coupled with Franz Waxman's haunting Das Lied von Terezin. Though this setting of the 92nd Psalm was originally composed in English, this recording is in Hebrew, as we will perform it. Note also, that although the text in the score is transliterated in Hebrew as it would have been spoken in pre-war, Eastern Europe, we will perform the work in modern Hebrew - and this recording is also in modern Hebrew. The sweep and emotion of the performance is gripping, and the soloists (baritone Michael Kraus, in particular) are appropriately cantorial.
