Why did Tool choose -(ions) for a track?

[thelambslain]

What is so significant about this track to justify its placement in the album? I know negative ions help balance serotonin levels in the body, which increases alertness and awareness in people.

to wake your third eye up for the next song.

I think you answered your own question.

[ignore-reality]

Tracks like (-) ions make Tool very unique. I love the shit that goes on in this track.

[THCvocals]

Listen to this on a nice surround sound system in a completely dark room... while tripping... you'll understand why it's so cool

[SansReality]

Its great if you really want to mess with a tripped out roommate, or the neighbors if your systems loud enough.

[Yiakovos]

Honestly, I think it's to make the CD seem like it had more new songs.
