Planet X’s Universe is a truly outstanding progressive metal instrumental effort. Tony MacAlpine’s heavy riffing and throwback shredding bode well with Derek Sherinian’s typical stellar synth playing. Drummer Virgil Donati also displays his considerable chops and has solo writing credits for two of the songs. One of them, Dog Boots, is in many ways the album’s standout tracks. It’s riff-heavy intro is quickly punctuated by the incoming keyboards with a nice melody. It gets stuck in my head a lot. I think it would be a good song to use in a film. Other standout tracks include Clonus, Bitch, King of the Universe, Pods of Trance, and 2116. My only complaint about the album is that there isn’t that much actual variety. Most of the songs have the same basic sound. Still, this is a worthwhile purpose for fans of heavy instrumental music or of any of the musicians involved.
