This album may have some filler that isn't really music and oddball noise filler tracks, but it also has some of the most inventive and progressive rock songs ever on it. There's an atmosphere on this album and the songs on this album that just overpowers the listener. This was Tool's creative peak and Tool is an extraordinary band so that's saying something. For some people, they'll fall in love with this immediately and for others it may take a couple listens to absorb it all.
