I'm playing Gerard Grisey's Anubis et Nout (on baritone), and recently purchased a score. However, it didn't come with any key or performance directions. While I can deduce most of what I need to know from recordings and writing about the piece, it seems like there should be something, considering that the score is not self-explanatory (for example, it is written in bass clef, and is usually read as two octaves above written). Does anyone have a copy of this with directions or notes from the composer? Thanks!
