Ralph, thank you for the wonderful survey.
I just wondered about the inclusion of the two versions mentioned in the title, Gielen with Jerusalem and Kallisch, and Sanderling with Schreier and Finnila. The Sanderling version received highest praise by Tony Duggan, and Gielen's recording - a Mahler interpreter in high esteem with Duggan - came too late for the Duggan survey. At least the orchestral part is excellent by any account, and it is quite easily available as a download. Anyway, it seems to me that both might deserve inclusion in a future edition.
Thank you for taking part in the MusicWeb International Forum.
