While one can share a former reviewer's frustration, one should agree not to take it out on the artist or material at hand.  This is the second Procol Harum record I bought, after a high school friend turned me onto A Salty Dog, which stands, perhaps, as their masterpiece (well, along with Grand Hotel and Exotic Birds and Fruit), though they never did make a duff record (well, Something Magic...).  The playing is majestic, it also rocks very very hard, being more guitar-oriented than other PH records, and Brooker's voice--what more can possibly said about it's bell-in-the-church-steeple clarity and resonance?  Great pianist, too.  If you are a rock and roll enthusiast, then here is where I'd recommend you begin to enter Procol Harum territory, particularly if all you know is "Whiter Shade of Pale" or "Conquistador."  Then buy everything they ever recorded.  The match of Brooker's music and Keith Reid's lyrics is one of the most serendipitous occasions in the quantum universe.
