"Vicarious" is the first track from progressive metal band Tool's 2006 album "10,000 Days" and is the final track in the Tool playlist of Guitar Hero: World Tour, following Parabola and Schism. The song is in 5/4 time for the majority of the song, and is notable as the longest song in the Tool section; Parabola is just over 6 minutes, Schism is almost 7, but Vicarious is just over 7 minutes. The odd time changes that suddenly occur within this and the other Tool songs can throw off a player that is trying to keep a beat. The end is very similar to Schism in manner; the last 15 seconds is a barrage of notes on the guitar and bass tracks and can either wipe out any FC left or prove a very exciting challenge.
