Tool has put out five studio albums. Their first release was Opiate, an extended play. It had only seven songs on it. Tool's first album, Undertow, was heavy metal. In 1996, they made Ænima. Rolling Stone said it was one of the 100 best metal albums of all time. The band took a break before and after releasing their third album, Lateralus. This was because singer Maynard James Keenan was working with his other band, A Perfect Circle.
