of Jones introduced them to bassist D'Amour. Early on, the band fabricated the story that they formed because of the pseudophilosophy "lachrymology". Although "lachrymology" was also cited as an inspiration for the band's name, Keenan later explained their intentions differently: "Tool is exactly what it sounds like: It's a big dick. It's a wrench. ... we are ... your tool; use us as a catalyst in your process of finding out whatever it is you need to find out, or whatever it is you're trying to achieve." After almost two years of practicing and performing locally in the Los Angeles area, the band was approached by record companies, and eventually signed a record deal with Zoo Entertainment. In March 1992, Zoo released the band's first effort, Opiate. Described by the band as "slam and bang" heavy music and the "hardest sounding" six songs they had written to that point, the EP included the singles "Hush" and "Opiate". The band's first music video, "Hush", promoted their dissenting views about the then-prominent Parents Music Resource Center and its advocacy of the censorship of music. The video featured the band members naked with their genitalia covered by Parental Advisory stickers and their mouths covered by duct tape. The band began touring with Rollins Band, Fishbone, Rage Against the Machine, White Zombie, and Corrosion of Conformity, to positive responses, which Janiss Garza of RIP Magazine summarized in September 1992 as a "buzz" and "a strong start". Undertow (1993–1994) The following year, at a time when alternative rock and grunge were at their height, Tool released their first full-length album, Undertow (1993). It expressed more diverse dynamics than Opiate and included songs the band had chosen not to publish on their previous release, when they had opted for a heavier sound. The band began touring again as planned, with an exception in May 1993. Tool was scheduled to play at the Garden Pavilion in Hollywood but learned at the last minute that the venue belonged to the Church of Scientology, which was perceived as a clash with "the band's ethics about how a person should not follow a belief system that constricts their development as a human being." Keenan "spent most of the show baa-ing like a sheep at the audience." Tool later played several concerts during the Lollapalooza festival tour, and were moved from the second stage to the main stage by their manager
