An awesome song by the experimental rock group The Fall of Troy on their album Doppleganger. It's a remix of F.C.P.S.I.T.S.G.E.P.G.E.P.G.E.P. (which is an acronym for absolutely nothing), which is also a good song. It is now well known after its appearance on Guitar Hero III.
Never heard of The Fall of Troy before until I played their song F.C.P.R.E.M.I.X on Guitar Hero!
