The 1996 sophomore effort by American rock band Tool. Tool's musical style is eclectic and difficult to categorize, usually being described as style-transcending. Ænima elaborates on the post-grunge sound characteristic of the early 90's alternative metal, employing psychedelic and industrial influences. There's a lot of atmospheric and spacey synths on this record, making it sound dreamlike. Usually the music is accompanied by elaborate artwork, and Ænima is no exception. The american CD release had a lenticular jewel case that made the artwork seem to move. The unique packaging was Grammy nominated.
