I've downloaded this for listening later on - very interested in hearing it - but I'm just pleased to see other Messiaen listeners here. My benchmark for when I can really play the piano is his Vingt Regard - he is a huge influence.
I like it! I head it merging into a long suspended string chord with the OM adding its character (do you have plans to continue the work or is it a standalone piece?). However, I have to confess that I am not that familiar with Messiaen's orchestral works to pick up the nuances. I listen to his piano/organ works mainly. Therefore, I found myself thinking more of Frank Zappa when listening to Klangfarben (I think it is also something he would have done but for Varese).
On a technical side, can I respectfully ask you to check your meters. I am hearing distortion in some of those bells at about 18 seconds, 21 seconds, the climax between 28 and 35 seconds (and at about 1m40s, is there a big click?).
I checked those levels and there may have been some distortion around the 27 -31 section. I am not sure if there is any distortion (other than the instruments sound itself) around the 18 second section. The chimes, glockenspiel, and crotales, I suspect, are the culprits. The 'distortion' may also be the sound of the sample itself, especially in the crotales and chimes. When these are played at the higher velocities they are very cutting and bright. This could be the partials of the instrument sound itself.
I uploaded another file and cut back on the velocity in those sections and the overall loudness of the mix.
I did not detect the click at 1:40. I think there's a bass drum thud there.
Messiaen, Crumb, Ligeti, Boulez, Carter, Berio and Cecil Taylor. (There. I said it!)
There's a piece by George Crumb, Makrokosmos III (for two pianists and two percussionists) that I listen to periodically for inspiration. It's a very exotic piece and certainly not for everyone's taste. But the percussion is really amazing.
