I have one of the five 'Tricorne' rolls and, although is does indeed
say 'Played by de Falla', it's very obviously not hand-played!  Rather,
like the contemporary Stravinsky rolls for Pleyel, it is a special
arrangement for the player piano.

Rex Lawson tells me that the roll was made from an arrangement created
specially by de Falla, which exists in one of the Spanish archives.
But the rolls were rather casually created, and require substantial
tempo changes between different segments.  They seem to be very scarce
-- a shame because they are great music.

 [ "Throughout the ballet, Falla uses traditional Andalusian folk
 [ music.  The two songs sung by the mezzo-soprano are examples of
 [ cante jondo singing, which typically accompanies flamenco music
 [ and tells a sad story.  At one point (the farruca), he quotes
 [ the opening of Beethoven's 5th Symphony."  -- Robbie
