I have these rolls with music composed by Manuel de Falla:

* 6755-4 Duo-Art, Ritual Dance of the Fire, played by Arthur Rubinstein

* 7147 Welte, Andaluza, Spanish Pieces No. 4, played by Carol Robinson

* 2770 Welte (Licensee conversion) Pieces Espagnoles, Nos. 1 & 2,
played by the composer, Manuel de Falla.

Kind regards,

 [ Thanks for your report, Grahame.  The conversion to Licensee format
 [ was possibly commissioned by Ken Caswell for his series of CDs of
 [ Welte-Mignon music.  His T-100 "Red" Welte-Mignon rolls were simply
 [ too fragile to withstand multiple recording "takes" (and Ken was
 [ wont to adjust the expression code if he felt it needed improvement),
 [ so Richard Tonnessen perforated copies in Licensee format.  Of
 [ course, Caswell changed the tracker bar in his Feurich Welte piano.
