I have a number of LP's of recordings of Welte rolls by famous
composers, and also some of the series that Joe Tushinsky, the
president of Sony Superscope, made on his Boesendorfer Imperial
Grand using a Welte Vorsetzer.  Some were actually Ampico Rolls
but a number of Welte rolls were done first.

also, I have three Telefunken LP's, recorded on a Steinway/Welte
piano, of Ravel, Debussy, Eugen d'Albert, Franz X. Scharwenka,
Emil Sauer, Ferruccio Busoni, T. Leschetizky, and Frederic Lamond,
Mahler, Richard Strauss, Reger, Skrjabin, Humperdinck, and Glasunow.
I don't know if these were ever put on a CD but they exist on three
LP's that I have in my collection.  Just thought I would add my two
cents.

Cheers,
Dave McPeak
