More comments from Ed Reichenbach:
The Orbon Partitas were recorded at Fine Recording Studio, NYC on December 6, 1966. This is indicated in the Mercury Discograpny of Michel Ruppli and Michael Novitsky, vol. IV page 699, Greenwood Prress 1993, and although Ruppli/Novitsky claim that the Partitas were left unissued, that they are wrong on this account is confirmed by the discography of the London Symphony Orchestra by Philip Stuart, now hosted on CHARM, under the entry for "Orbón: Tres Cantigas, 10 July 1964: Coupled with Orbón's Partitas, recorded by Puyana in the USA in Dec 66."
On December 7 1966, Puyana also recorded pieces of Cabezon and Arauxo, for which Ruppli/Novitsky do not provide any details and claim were also left unisued, but the Arauxo "Quinto tiento de septimo tono" on the LP could well have been the Arauxo piece recorded on that day. In fact your listing and other online information do not make it clear if the Quinto tiento is a piece for solo harpsichord or for ensemble as the two by Selma y Salaverde.
Contrary to what the Dorati society indicated, there was never any release of the Orbón Tres Cantigas under the Mercury label (unless they were refering to a "pressing" made by Mercury but published as that Philips LP).
