Additional vocals on `bottom' by Henry Rollins

Tool opened for the Rollins Band a few years ago, and they must have formed a good enough relationship with Rollins to persuade him to work with them on bottom. Rollins performs a spoken word piece in the middle of the song, in addition to backing vocals in the chorus that are quite faint, and can only be heard by listening very carefully.
