Gah! Update:
Sheetmusicplus have cancelled my order because they can't get a date out of the publisher (Hal Leonard).

I've re-ordered through Stantons. Hopefully they have them in stock and I will actually get them!
I'm gonna start having nightmares about these!
Also picked up a copy of Tausig's transcription of Ride of the Valkyries. Been looking for this for ages and finally found it on the German Amazon (through a re-seller).
i know! the suspense is killing me!!!!
just returning from some travels and musical hunting shinanigans. the getting was good. nice new old stock and vintage gems unearthed!
Mozart arranged by Guy Maier
Allegro from Sonatina in C minor for Piano and Violin, transcribed for two pianos (4 hands)
"This Allegro is taken from Mozart's littel known Sonatina in C minor written in 1768 at the age of 12. Its imitative and answering voices lend themselves readily to the two-piano medium....)-G Maier
Carl Fischer (vintage new old stock) Ed. 1933 , two copies with Primo and Secundo scores in each (4 scores total. I paid 25 cents for each. not bad for a 50 cent investment).
Melody of Love, Paraphrase

super nice condition for old/vintage out of print books. I will bit by bit buy them all eventually and put a whole set together. The whole collection can be found but usually too expensive, I will just pick up nice volumes as I go along. Two down. 6 or 7 to go!

David Amram
Sonata for Solo Piano (1960)
CF Peters
Brilliant and lyrical (i.e. easy to lisen to) Jazz/Classical Fusion work. Approx 18 minutes. I am on the hunt for a full recording. Possibly taking this beast on:
https://www.sheetmusicplus.com/title/Sonata-for-Piano/1006989I have uploaded a fine dissertation on the work
(from my feed description of it a reviewer's excerpt:David Amram’s Three Movement sonata gathers gospel licks, wide-open-spaced modal portals, Ivesian bell tones, slow, wayward bass lines, Latin-influenced melodies, and blusey Coplandisms. The composer stirs these elements into a pot and comes up with a delicious, eclectic, and organically integrated musical stew. ...I’m baffled that so few pianists have taken up its cause)
