By Tool, 1997. The song is mostly in 4/4 time with some sections of 7/8 in between. In the intro, Danny Carey plays 4 measures of 7/8 on his ride cymbal over the rest of the band playing in 4/4, and they all meet up on the downbeat of the 5th measure in 4/4. During the bridge there are 3 measures of 7/8 followed by one measure of 4/4. During a particular quad fill, the drums are in 3/8, the guitar plays one measure of 9/8 followed by one in 5/8 all while the bass keeps time in 7/8.
