fantastic thank you that's extremely helpful that biography contains details of his early and late life that do not exist in the other sources i've got his time in paris pretty well fleshed out slonimsky's reminiscences in perfect pitch are full of juicy details i'm still trying to understand all the orthodox religious references in some of my other sources e g two resurrections i'm a little out to sea on some of that it's hard to write about his tone method without doing forbidden original research because it seems no one has really studied it in depth sitsky maybe more than anyone else i really want to look at one of the scores now if only i had a public domain illustration or two anyhow now i can cite that biography thanks to you i'm presuming that the world encyclopedia in russian is a reliable source everything sounds right and matches up with grove and the others i've got cheers talk
