I just finished my recording of Scriabins 5th Symphony "Prométhée - Poeme du feu" which is as Symphony with textless Choir and "Luceclav" (Colorpiano) a pretty great piece of music. It's Pianosolopart makes nearly to a large Pianoconcert, meanwhile it does not seem to be understood as Pianoconcert.
I looked at some existing interpretation and was quite astonished to see, that nearly all are more or less often much to slow (long). Respecting the metronome figures it should not be more than 17-18 Minutes as it really is for instance in a realisation of the Yale Campus, while Svjatislav Richter for instance needs more than 24 Minutes.
The second shortcomming of most interpretations seem to me the realisation of the luceclav. Nearly all over the score there are not more than two Colors together "played".
There seem to be some but already not that many interpretations who respects the demanded Colorpiano. But even most of them seem give one or another "lightshow" as we know it from Pop- and entertainment shows, but none seems to be able simply and really to "plunge" the whole Room in the one or two colors Scriabin has written in the Score for the Luceclav to let the listener concentrate completely on the connection between Color and sound.
In Memoriam of the Scriabins Death April the 27th 1915 I produced my own recording of this piece trying to concentrate a bit more on the real tempo advices and just the few Color that really are demanded in Scriabins score.
Since I am trying to avoid to directly "link" external Content here in respect of existing Rules here, I simply tell you that You can find my realisation on my website (see thee Link at the bottom of my postings and search the menu for S/Scriabin or simply with "klassik-resampled.de/promethe")
Perhaps you might be interested in my little attempt to realise this masterwork of early modern music.
