Background: Slipknot is an American heavy metal band from Des Moines, Iowa. The band was formed in 1992 by percussionist Shawn Crahan, drummer Joey Jordison and bassist Paul Gray. After several lineup changes in its early years, the band settled on nine members for more than a decade: Corey Taylor, Mick Thomson, Jim Root, Paul Gray, Craig Jones, Sid Wilson, Shawn Crahan, Chris Fehn and Joey Jordison. Gray died on May 24, 2010, and was replaced during 2011-2014 by guitarist Donnie Steele.
Context: Anticipation for Slipknot's second album was intense. In early 2001, the band began recording the second album at Sound City and Sound Image studios in Los Angeles. Around this time, conflicts arose between band members due to extensive touring and recording schedules. Recording of their second album ended in February 2001 and the band embarked on their Iowa World Tour. Entitled Iowa, Slipknot's second album - released on August 28, 2001 - peaked at number three on the Billboard charts and at number one in the UK. The album produced three singles; "The Heretic Anthem" (promotional single), "Left Behind", and "My Plague", which appeared on the soundtrack for the film Resident Evil. In 2002, Slipknot appeared in Rollerball (2002), performing "I Am Hated". The release and intense promotion of the album resulted in sold-out shows in large arenas in several countries. In mid-2002, Slipknot went on hiatus because of internal conflicts, and band members focused on side projects. Vocalist Taylor and guitarist Root revived their band Stone Sour, drummer Jordison created Murderdolls with vocalist Wednesday 13, percussionist Crahan founded To My Surprise and DJ Wilson went solo as DJ Starscream. For a while, the future of Slipknot was uncertain and there was much speculation about whether there would be a third album, or if the split would become permanent. "I don't have a problem with anyone in Slipknot," Jordison protested. "I've seen comments from Corey saying there are things to be resolved, but I have no fucking idea what he's talking about." Nonetheless, on November 22, 2002, Slipknot released their second DVD, Disasterpieces.
Question: What did they do during their hiatus?
Answer: band members focused on side projects.

Problem: Background: Ace of Base was a Swedish pop group, originally consisting of Ulf "Buddha" Ekberg and three siblings: Jonas "Joker" Berggren, Malin "Linn" Berggren and Jenny Berggren. The group released four studio albums between 1992 and 2002, which sold more than 30 million copies worldwide, making it the third-most successful Swedish band of all time, after ABBA and Roxette. Happy Nation (reissued as The Sign) is one of the best-selling debut albums of all time, and was certified nine times platinum in the United States.
Context: Even though the band members were exhausted from two long years of international promotion, they could hardly believe how successful they had become. In April 1994, an obsessed German fan broke into the Berggren family home, brandishing a knife. After managing to restrain her, the band decided they needed bodyguards. However, they were unable to take time to reflect before starting work on a second album because their record companies all over the world were demanding a swift follow-up. To speed up the process, instead of Jonas and Ulf writing the bulk of the album, each member was encouraged to submit their own tracks for consideration. In the end, 17 tracks made the cut of the second album, titled The Bridge. It marked a considerable change of direction in sound; out were the reggae and club sounds that made the group so popular in favor of a more experimental sound and several ballads. The lead single, "Lucky Love", however, was a mainstream pop record, and upon its release in October 1995, it became the band's first No. 1 single in Sweden. This came as a pleasant surprise to the members, as they had found that their fellow Swedes had been their harshest critics. It charted at a more modest No. 13 in Germany, No. 20 in the United Kingdom and No. 30 in Australia. Arista Records instead opted for the pulsating dance beat of "Beautiful Life" for the first single in the US, where it peaked at No. 15. "Beautiful Life" was released as the second single from the album in most countries, reaching No. 15 in the UK and No. 11 in Australia, while "Lucky Love" was remixed in a new acoustic form along with a new video for the second US single from the album, peaking at No. 30. The Bridge was certified platinum in 14 countries, but the phenomenal success of the band's first album proved difficult to follow. "Never Gonna Say I'm Sorry" was released as the third single from the album and achieved moderate success in Europe, but it failed to chart on the Hot 100 in the US. In February 1996, the band performed at the Vina del Mar Festival de la Cancion in Chile, topping the bill alongside 2 Unlimited.
