A 16 year, old ska-rock-new wave, band that was formed in the late 1980s in Orange County,CA. The band members are Tony Kanal, Adrian Young, Tom Dumont, and Gwen Stefani. After the release of their first album No Doubt's Gwen and Tony broke up. While in production of their following album(Tragic Kingdom) Gwen wrote many heart-breaking songs about Tony. No Doubt's break through album was Tragic Kingdom in 1995! They have been releasing more albums ever since and their most recent work is The Singles 1992-2003.This great talented band performed at The Super Bowl in 2003 with Sting and is still together to this day. No Doubt has won many awards such as MTV VMAs, RMAs, a Grammy, and many more. They have been around for a long time and will be around for much longer.
No Doubt sings the modern version of the 80s song "It's My Life".
