I’m new to Planet X and bought this mainly because I read Holdsworth played on it. Actually, he only plays on two tracks, and on one of these tracks, he only solos for 44 seconds. Brett Garsed plays guitar on the other tracks. Anyway, I’m really enjoying this disc. The music is instrumental rock/metal that sounds similar to Andy West’s Rama 1. The credits list Virgil Donati (drums) and Derek Sherinian (keys) as Planet X, and in the liner notes, their photos are bigger than the guest musician’s photos. Ha! Virgil wrote eight of the nine songs, the other is a collaborative effort. There are some tricky grooves happening with insane time changes executed with ease, and at times it seems the complex music was written so they could show off, but why not if your talented and have the chops? On bass guitar, Rufus Philpot plays on two songs and the outstanding Holdsworth alumni Jimmy Johnson plays on the remaining tracks. If you crave high-energy instrumental music, you should check this out.
