A little murky as to what he captured from 5/12 and 5/19:
On a tape clearly marked 5/19:
Rach PS2 (only 7 mins captured)
Chopin-Barcarolle, Nocturne 55#1; Waltz C#m, Polo op 44
Scarlatti=-4 Sonatas
Schumann-Traumerei
Bizet/VH-Carmen Vari
Moszkowski Etude FM
There was also another tape ambiguously labeled as VH from “May, 1968”:
Beethoven PS28
Scarlatti and Chopin as above
Rach PS2 (this one complete)
Encores-Traumerei, Cho Waltz C#m, Mazurka FM, Carmen
His documentation was pretty good—inserted program pages, but made difficult for these 2 for since they were identical printed programs, both dates appear on printed program page.
Not sure I have your most recent VH research but old version I had suggests 19th above seems right (albeit incomplete) and the second grouping likely the 5/12 in view of this Rach complete and the Mazurka in the encores.
Haven’t compared the perfs yet to portions I already had of the recitals.
That’s super cool. I never thought I’d see the master for these surface!
CBS recorded the May 12 recital, so with a bit of work it’s possible to determine what was recorded from which recital. My guess is that May 19 is correct however and that other tape is May 12, since Carmen was only played on May 12 and Moszkowski only on May 19.
The order certainly is odd though. I suppose he’s recopied these to new tapes at some point, unless they were recorded by a local friend of his.
