Yesterday and today, posted (not reposts from Amazon, but reviews written back in 2013 and pending):
Mravinsky‘s extraordinary Symphony Liturgique recorded live in 1965 with its many CD editions
Ansermet’s complete stereo Honegger, Arthur Honegger: Symphonies Nos. 2-4, Pacific 231, Le Roi David, Une Cantate de Noël. Frank Martin: In Terra Pax. Ernest Ansermet, Orchestre de la Suisse Romande. 3 CDs Eloquence 480 2316 (2012)
Locating all (I hope) the CD reissues, including those from Japan (sleuth work!); finding suitable front and back cover scans or photos (back covers are sometimes hard to find, but that’s where the essential information is located); linking all the references to other versions, inserting photos… Lots of work!
