As the Catalan paperwork Thomas provided shows, this is a recording of a live performance, given on June 17, 1928. The usual abrupt sonic cut-offs and starts between sides are present, and if my memory is correct, some of the sides are dubbings. (However, said memory might be confusing it with Koussevitzky's Missa Solemnis on Victor, where dubbings occur nearly every other side.) The Millet performance is a satisfying and powerful one, and the sound is full and reasonably detailed. Also, there is an interesting detail: the chorus's soprano parts are sung by boys, not women. (I don't remember about the altos.) A good contemporary transfer of this set would be very welcome. Not only from a discographical standpoint: I found the performance rewarding enough to play the set through, changing all of those sides, three times.
And yes -- as Clark Johnsen wrote, it is Victor M-29.

Looking for a Victor album number. -- the Missa Solemnis, the old Barcelona recording. WERM has only the master numbers, although elsewhere I found mention of an M29. Can anyone confirm? Also does anyone know of a youtube or other online audio source? Even a CD? Thank you.
