I have to agree with the negative reviewer who said words to the effect of, 'I hate to give a negative review to a book about prog but I have to.' Having read considerable progressive rock internet information and reviews for the last 6 months, and almost exhausted that source (except for the hard-to-read Gibraltar Encyclopedia) I picked up the book looking for a little more in-depth info on history and bands, but there was little of either. Before buying this book you should really be aware that the history is very brief, simplistic, and repetitive, and is really informative only to a complete novice in prog or even rock history. Some of the statements, such as that "Days of Future Passed" is the first progressive album, are quite silly. Because of the layout of the pages in this section, for some unfathomable reason only about two-thirds of each page contain text, the rest highlight names, thus reducing drastically the information content. The band reviews at the end are equally laughable since they consist of at most two or three sentences, most of which believe it or not are a sentence of the nature, "sounds like Genesis." In fact those three words are repeated probably four times per page in the last 50 pp of the book!! Without a downloadable mp3 site like audiogalaxy it would be absolutely hopeless to weed through the hundreds of entries about prog bands in the reviews section since the music is described so unimaginatively and without any kind of indication of the overall quality or status of a given band. God help the unfortunate individual who buys a CD based on Jerry Lucky's [...]reviews! Anyhow, there being so few books about prog, it's really disappointing to say this one is so awful, but it is. Don't buy!
