The format of a chronological description of major dates in the psychedelic "time-line" is fine but this book suffers from total absence of editing, including spell-check, and originality! Duh, "heroine" for "heroin," "David Gilmore" for "David Gilmour" are just a few obvious flubs. Now and then the author interjects into the descriptive chronology the odd value judgement when it concerns his own fave-raves. The final section, a short review-list of major and minor psychedelic bands, is lifted from better books, like Joynson, etc. In short, this is for the undemanding reader.
