The first released CD by Tool was Opiate, a five track CD. It was the first of four CDs to make people begin questioning the ritualistic tendencies the band had. The question of Satanism certainly arised.
Undertow was the second CD released by Tool and featured several hit tracks...some even had music videos made out of them. However, I do not know much about this particular CD other than it continued with the dark and evil sounds of the first CD.
The next CD released by Tool was Aenima, featuring the singles, Stinkfist and several others. This is my nominee for the album with the most strange song titles.
The latest release is titled Salival and is a CD/DVD set. It has
a few songs from previous albums as well as a couple new songs, one of which is Message To Harry Manback II, a continuation of the first Message To Harry Manback. Most of the songs from earlier CDs are live.
