No Doubt is an American rock band from Anaheim, California, that formed in 1986. Since 1994, the group has consisted of vocalist Gwen Stefani, bassist and keyboardist Tony Kanal, guitarist and keyboardist Tom Dumont, and drummer Adrian Young. Since the mid-1990s in live performances and the studio, they have been supported by keyboardist and trombonist Gabrial McNair and keyboardist and trumpeter Stephen Bradley.

The ska sound of their first album No Doubt (1992) failed to make an impact. The Beacon Street Collection (1995) is a raw expression of their sound, inspired by ska punk and released independently by the band under their own record label. The album sold over 100,000 copies in 1995, over three times as many as their first album sold. The band's diamond-certified album Tragic Kingdom (1995) helped launch the third-wave ska revival of the 1990s, and "Don't Speak", the third single from the album, set a record when it spent 16 weeks at the number one spot on the Billboard Hot 100 Airplay chart.

No Doubt is the self-titled debut studio album by the American rock band No Doubt, released March 17, 1992 on Interscope Records. The album was originally recorded as an independent release, but was re-recorded after the band was signed to Interscope. It was produced by Dito Godwin and recorded in a recording studio in Los Angeles.

The album was released during a period in which the United States was mainly focused on grunge music, an angst-ridden genre that was almost the complete opposite of No Doubt's upbeat commercial sound. Despite strong tours, the album failed to perform as well as the record company expected it to, selling only 30,000 copies. The record company refused to fund the release of a single from it, so No Doubt released the album's only single, "Trapped in a Box", independently. Since the band signed out of Interscope, the band independently produced and released a follow-up to No Doubt, The Beacon Street Collection, in 1995. This album had a better commercial performance than the band's debut album, selling 100,000 copies, leading Interscope to finance and support their third album, Tragic Kingdom.
