Tool

Formed around 1990 in Los Angeles, California, United States, by drummer Danny Carey, guitarist Adam Jones, vocalist Maynard James Keenan, and original bassist Paul D'Amour, Tool is a band that is most noted for combining alternative metal with a wide variety of progressive structures, irregular time signatures and lyrics that range from angry diatribes to meditations on philosophical and social matters.

After performing a handful of shows in the Los Angeles area and up the West Coast, they toured in the United States with Primus in the summer of 1992 in support of their EP Opiate. Their first full length recording, Undertow, was released in 1993.
