Although his designation of this book as "the worst product" he has ever purchased in relation to progressive rock seems excessive (it's surely better than most posters), the previous reviewer (see below) is largely correct, more's the pity. Mr Lucky's book is of the recent genre I like to describe as My Record Collection books. The author of such a book selects a title vague enough to justify inclusion of whatever happens to be sitting on the CD shelves (or gathering dust in the cellar), reads the liner notes and/or listens to them again, and writes up the resulting insights. "50 Underrated Jazz Records of the 1960s," "Truly Weird Music," "Out There: Experiments in Rock," etc. -- that sort of title. These are usually in the form of lists with commentary lengthy or brief -- because these are easy to write -- and easy to read (always a consideration in contemporary publishing; and as for rock fans who move their lips when reading traffic signs...no, I needn't be nasty here.) Chronological ordering is always a possibility, although research may take a few hours longer. Random ordering is the easiest but may require an explanation ("I have attempted to discuss these discs in an ahistorical yet subtextual manner whose underlying rationale will emerge as we proceed...") Alphabetical ordering is chosen here, which is convenient, sort of, depending. The book in question is rather unbalanced in its choices, with the criteria of inclusion unclear (but this is a MRC book, remember.) The famous mingle with the obscure, the hugely talented rub elbows with the mediocre, landmark recordings are there right along with the full fathom five variety, and some of the bands are only borderline progressive (although this might broaden the appeal of the book to those who accept the received wisdom the progressive rock is "stupid" or "pretentious;" some is and some ain't.) There's nothing wrong with the foregoing if the book attempts in some way to be definitive, or even a decent guide for the novice. This book attempts neither. Mr Lucky's pre-emptive remarks that he does not intend to be critical, which he somehow equates with "nit-picking" (does he mean "detail"?), although his very choice of artists to include must imply some implicit critical framework. He also in his introduction to this book recirculates the old saw that one has no right to criticize what one can't do oneself. For myself, that would mean I have no right to criticize restaurant food, mechanical work on my car, the telephone book, etc. It's not a question of having a "right," but of what one wants to do, and a critical frame of reference is not inconsistent with disinterested observation. Well, I think that's enough, or more than enough. Mr Lucky's heart is in the right place, and progressive fans need all of the allies (and propagandists) that they can get. Mr Lucky recommends in his letter to Amazon re The Progressive Rock Files several books which are better (although all have their problems.) Novices (and others) might wish to take a peek at magazines such as Audion or Expose or Progression. Or they might wish to buy the greatest recording ever made (yes, I'm exaggerrating), Robert Wyatt's "Rock Bottom" (1975), available at better websites everywhere.
