Lateralus  by Tool

Tool's 2001 album Lateralus is considered one of the greatest albums of progressive metal and stands out for its complexity and philosophical depth. The production was done by David Bottrill in collaboration with the band. It was their last collaboration with Bottrill. With a total duration of 78:51, it is one of the longest CDs ever recorded.

• The recording of the album took place between October 2000 and January 2001 at Cello Studios and other studios in Hollywood. The title track Lateralus follows the Fibonacci sequence in the number of syllables of the lyrics and in the rhythmic measures (9/8, 8/8, 7/8). The main singles were Schism, Parabola, and Lateralus. Schism won the Grammy Award for "Best Metal Performance" in 2002. The iconic cover with the "transparent" layers of the human body is the creation of artist Alex Grey.

The album debuted at No.1 on the US Billboard 200, selling over 555,000 copies in the first week. It has been certified triple platinum in the US by the RIAA.
