Tool is an American rock band from Los Angeles, California. Formed in 1990, the group's line-up includes drummer Danny Carey, guitarist Adam Jones, and vocalist Maynard James Keenan. Justin Chancellor has been the band's bassist since 1995, replacing their original bassist Paul D'Amour. Tool has won three Grammy Awards, performed worldwide tours, and produced albums topping the charts in several countries.
The following year, at a time when alternative rock and grunge was at its 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 L. Ron Hubbard's 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 and the festival co-founder Ted Gardner. At the last concert of Lollapalooza in Tool's hometown Los Angeles, comedian Bill Hicks introduced the band. Hicks had become a friend of the band members and an influence on them after being mentioned in Undertow's liner notes. He jokingly asked the audience of 10,000 people to stand still and help him look for a lost contact lens. The boost in popularity gained from these concerts helped Undertow to be certified gold by the RIAA in September 1993 and to achieve platinum status in 1995, despite being sold with a censored album cover by distributors such as Wal-Mart. The single "Sober" became a hit single by March 1994 and won the band Billboard's "Best Video by a New Artist" award for the accompanying stop motion music video. With the release of Tool's follow-up single "Prison Sex", the band again became the target of censorship. The song's lyrics and video dealt with child abuse, which sparked controversial reactions; Keenan's lyrics begin with: "It took so long to remember just what happened. I was so young and vestal then, you know it hurt me, but I'm breathing so I guess I'm still alive ... I've got my hands bound and my head down and my eyes closed and my throat wide open." The video was created primarily by guitarist Adam Jones, who saw it as his "surrealistic interpretation" of the subject matter. And while some contemporary journalists praised the video and described the lyrics as "metaphoric", the American branch of MuchMusic asked Keenan to represent the band in a hearing. It deemed the music video too graphic and obscene, and MTV stopped airing it after a few showings. In September 1995, the band started writing and recording their second studio album. At that time Tool experienced its only lineup change to date, with bassist D'Amour leaving the band amicably to pursue other projects. Justin Chancellor, a member of former tourmates Peach, eventually replaced D'Amour, having been chosen over competitors such as Kyuss's Scott Reeder, Filter's Frank Cavanaugh, Pigmy Love Circus's E. Shepherd Stevenson, Jane's Addiction's Eric Avery and ZAUM's Marco Fox.

What was their second album called?

Answer the question at the end by quoting:

Thompson was born in Sheffield, Alabama, on August 19, 1942, the son of Ruth Inez (nee Bradley) and Fletcher Session Thompson (born Lauderdale County, Alabama, August 26, 1919, died Lawrenceburg, Tennessee, May 27, 1990), who was an automobile salesman. Thompson had English and distant Dutch ancestry. He attended public school in Lawrenceburg, graduating from Lawrence County High School, where he played high-school football. Thereafter, he worked days in the local post office, and nights at the Murray bicycle assembly plant.
In 1973, Thompson was appointed minority counsel to assist the Republican senators on the Senate Watergate Committee, a special committee convened by the U.S. Senate to investigate the Watergate scandal. Thompson was sometimes credited for supplying Republican Senator Howard Baker's famous question, "What did the President know, and when did he know it?" This question is said to have helped frame the hearings in a way that eventually led to the downfall of President Richard Nixon. A Republican staff member, Donald Sanders, found out about the White House tapes and informed the committee on July 13, 1973. Thompson was informed of the existence of the tapes, and he, in turn, informed Nixon's attorney, J. Fred Buzhardt. "Even though I had no authority to act for the committee, I decided to call Fred Buzhardt at home," Thompson later wrote, "I wanted to be sure that the White House was fully aware of what was to be disclosed so that it could take appropriate action." Three days after Sanders's discovery, at a public, televised committee hearing, Thompson asked former White House aide Alexander Butterfield the famous question, "Mr. Butterfield, were you aware of the existence of any listening devices in the Oval Office of the President?" thereby publicly revealing the existence of tape recordings of conversations within the White House. National Public Radio later called that session and the discovery of the Watergate tapes "a turning point in the investigation." Thompson's appointment as minority counsel to the Senate Watergate committee reportedly upset Nixon, who believed Thompson was not skilled enough to interrogate unfriendly witnesses and would be outfoxed by the committee Democrats. According to historian Stanley Kutler, however, Thompson and Baker "carried water for the White House, but I have to give them credit--they were watching out for their interests, too... They weren't going to mindlessly go down the tubes [for Nixon]." When the Watergate investigation began to pick up speed, tapes revealed that Nixon remarked to his then-Chief of Staff Alexander Haig, "Oh shit, he's dumb as hell." Journalist Scott Armstrong, a Democratic investigator for the Senate Watergate Committee, is critical of Thompson for having disclosed the committee's knowledge of the tapes to Buzhardt during an ongoing investigation, and says Thompson was "a mole for the White House" and that Thompson's actions gave the White House a chance to destroy the tapes. Thompson's 1975 book At That Point in Time, in turn, accused Armstrong of having been too close to The Washington Post's Bob Woodward and of leaking committee information to him. In response to renewed interest in this matter, in 2007 during his presidential campaign, Thompson said, "I'm glad all of this has finally caused someone to read my Watergate book, even though it's taken them over 30 years."
