27 pieces, 27 excerpts. I'm pretty sure I could identify each piece, so this should be fair game.
Yes I am sure you could, having picked them...
It's a wicked selection indeed, but with some fascinating material. It would seem my knowledge is sorely lacking as I could only identify about half of them, and not all with total accuracy.
2 - Alkan: Sonata Op.33 Les Quatre Ages, 1st mvt.
5 - Ginastera: Sonara para piano, 2nd mvt
6 - Medtner surely ? But cannot name the piece.
7 - Granados: La maya y el Ruisignor, from Goyescas
9 - Medtner: Skazka Op.26 No.1
11- Alkan: Le festin d'Esope, Var.XXII
12 - One of Medtner's piano concertos, not sure which one of the 3
15 - Medtner: Sonata Tragica
16 - Mompou: Cancion y Danza No.7
17 - Franck: Prelude, Choral and Fugue (the fugue)
18 - Surely Medtner, but what ????
19 - This must be Kapustin but could well be Evans or someone else jazzy
21 - Medtner: Skazka Op.20 No.1
22 - Likely Schumann or Mendelssohn, but maybe not...
24 - Medtner: Sonata Triade, OP.11 No.2
26 - I know this but can't pinpoint it. Finale of Rach's first concerto ?
27 - Must be a Medtner sonara, but which ? One of the Op.53 ?
10 positives then, and some more or less educated guesses. Say schmontz, have you perchance a thing about Medtner ?
