Angel Rat is no less strangely intelligent concept wise. They have based the lyrics on some Irish and Russian folk tales, and primarily on the Chaos Theory by James Gleick – heavy stuff indeed. Music-wise, it is a shock – 12 very complex melodies evident as usual, but the whole direction of the sound has changed. Perhaps it reflects Blacky's departure from the group. Now sporting three members: Piggy, Away, and Snake, the new Voivod is moody, melodic, harmonious, and layered.
