Hello everyone –
I've been on a massive Liszt kick lately, but while listening to Leslie Howard's recording of the Robert le Diable reminiscences, I realized that while the Valse infernale is familiar and in print, perhaps the beautiful cavatine is NOT.
Further sleuthing found that both the cavatine and valse infernale were published in the Liszt Society's 1996 journal. Since then, has it been published more widely? Any information or guidance in finding a copy would be greatly appreciated.
AFAIK, the Cavatine is still to be published in the Supplement Vol.9 (Berlioz: Harold en Italie und andere Werke) to the Series I and II of the New Liszt Edition (EMB). IMO your best option is to contact the Liszt Society and ask for suggestions on how getting that score.
