No Doubt is an American rock band from Anaheim, California, founded in 1986. The ska-pop sound of their first album, No Doubt (1992), failed to make waves due to the popularity of the grunge movement at the time. The band's diamond-certified album Tragic Kingdom, released in 1995, helped launch the ska revival of the 1990s, and "Don't Speak", the third single from the album, set a record when it spent sixteen weeks at the number one spot on the Billboard Hot 100 Airplay chart.
The group released its next album, Return of Saturn, five years later, but despite positive reviews, the album was considered a commercial failure. Fifteen months later, the band reappeared with Rock Steady, which incorporated reggae and dancehall music into their work. The album was primarily recorded in Jamaica and featured collaborations with Jamaican artists Bounty Killer, Sly and Robbie, and Lady Saw. The album produced two Grammy-winning singles, "Hey Baby" and "Underneath It All", as well as scoring another hit with a cover of Talk Talk's "It's My Life".
In 2004, the band went on hiatus shortly after vocalist Gwen Stefani started her own solo project. During this period, she released two albums with a more pop-oriented sound, while the other members collaborated with other musicians. In 2008, they started recording their next album, which was delayed due to Stefani's pregnancy and tour commitments. The album, Push and Shove, was ultimately released in 2012, and its leading single, "Settle Down", peaked at #34 on the Billboard Hot 100, while the album reached #3.
Gwen Stefani and the rest of No Doubt appear as unlockable characters in Band Hero. The entire Band can be unlocked by first playing "Don't Speak" and then "Just a Girl" in Career Mode. However, shortly before the game's release, the band itself filed a collective lawsuit against Activision over the fact that, once unlocked, the band members can perform individually (i.e. having only one of the members sharing the stage with other characters, rather than with their bandmates) any of the other in-game songs, thus conflicting with a truer portrayal to the band, similarly to Kurt Cobain's case in the concurrently-released Guitar Hero 5.
