This mp3 part of the interview discusses the relationship between the HUGE collection of Slonimsky materials at the Library of Congress and the 4 Books that Electra Slonimsky Yourke, Nicolas Slonimsky's daughter, has recently edited.
This Book 4 contains other humorous, wacky, weird and, in some cases, serious and substantial material written by Nicolas Slonimsky that didn't quite fit into the other volumes. Like Frank Zappa, Nicolas Slonimsky defined his own world!
Nicolas Slonimsky was a friend of Frank Zappa's, and this mp3 relates some of that. Both individuals, many believe, were among some of the strongest cultural influences of our day in the realm of music.
