No Doubt is an American rock band from Anaheim, California, formed in 1986. Best known for their genre-blending sound that mixes rock, ska, and pop, the core lineup includes vocalist Gwen Stefani, guitarist Tom Dumont, bassist Tony Kanal, and drummer Adrian Young. Eric Stefani, Gwen’s brother, was an early member, while Gabrial McNair and Stephen Bradley have played as touring musicians since the mid-1990s. After a slow start, the band broke through with their third album, Tragic Kingdom, in 1995, which produced major hits like Don't Speak and Just a Girl and sold over 10 million copies, cementing their place in '90s music. Follow-up albums, including Return of Saturn and Rock Steady, saw the group evolve with reggae, dancehall, and pop influences, earning critical acclaim and Grammy awards. Following a brief hiatus for solo projects, including Gwen Stefani’s successful pop career, No Doubt reunited to release Push and Shove in 2012. To date, No Doubt has sold over 33 million records worldwide and is celebrated for their energetic style and influence on modern rock and pop music.
