In this Hispavox recording -- which I believe dates to the late 1950s or early 1960s -- Alicia de Larrocha (1923--2009) performs "Clair de Lune," the third movement of Suite Bergamasque by Claude Debussy. I created this video from the LP shown above, issued on the Musical Heritage Society label, serial number MHS 1761.
The Library of Congress online catalogue entry for this recording is here: http://lccn.loc.gov/99574671
So that there is no question in the mind of the listener, I rely principally on images of the LP and LP jacket in order to document the authenticity of historically important recordings such as these.
