There seems to exist an SACD recording of "Das Lied" in Cantonese by the same orchestra and conductor. The 3 reviewers on Amazon.com were't directly extatic about the performance, so if you go and buy this M10 let us know what you think.
One of the reviewers wrote: "IMHO only two or three Asia-based orchestras could meet the technical demands of any Mahler score. The Singapore Symphony, unfortunately, is not one of them. It just cannot produce the Mahlerian sound that is in the score."
