Queen is a reasonably talented band who have chosen their models unwisely. On “Side Black,” they venture into a lyrically muddled fairy-tale world with none of Genesis’s wit or sophistication. They’ve also appropriated the most irritating elements of Yes’s style — histrionic vocals, abrupt and pointless compositional complexity, and a dearth of melody. “Side White” is quite an improvement, containing many of the same muddled tendencies, but with the saving grace of timely and well-chosen power chords and some rather pretty tunes. But the album remains a floundering and sadly unoriginal affair.
