Anaheim, CA rock-ska band No Doubt saw immense success in 1995 with their album "Tragic Kingdom," which was released in 1995. The diamond-certified album also spawned the single "Don't Speak," which spent 16 weeks at the top of the Billboard Hot 100. Their addictive pop-rock sound can be heard on their follow-up albums, "Return To Saturn" and "Rock Steady." The band took a break in 2004 while lead singer Gwen Stefani released two solo records during the hiatus. No Doubt reunited to release "Push and Shove" in September 2012. The band is currently working on new music.
