Haven't got time to read much of it now but it looks great. I have "Krautrocksampler", "The Crack in the Cosmic Egg" and "Cosmic Dreams at play" on my bookshelves but always nice to get a fresh perspective.
See that this starts with Agitation Free - the one serious omission from "Krautrocksampler" in my opinion (checkout my review of Agitation Free's "Last" in this websites Unsung Review section).
