Query: Pure Revisionism

This book is a revisionists fantasy...the author discounts Cream, The Doors and The Grateful Dead while extolling such unknowns as Plasticland and The Flaming Lips...the book reads like a payola scandal waiting to happen...I imagine that since Jim Morrison cannot buy the author a drink or a dinner that The Doors cannot be considered a heavyweight psychedelic band...Imagine acidheads..The Grateful Dead were not psychedelic!!!!!!! read it at Borders then do not buy.
