by Stephen Thomas ErlewineWalk on Water finds the classic mid-'70s UFO lineup -- featuring Michael Schenker -- reuniting for another go-round. Much has changed in rock & roll since Schenker last played in UFO, but in UFO's world, things remain the same. The group continues to pound out heavy rockers without changing its formula much at all. To the disinterested observer or critic, this means Walk on Water is boring, but UFO diehards may be pleasantly surprised by the record, since it finds the band playing with energy and conviction, even if the music is predictable.
