Gwen Stefani's family was instrumental to her music career, with her parents introducing her to music and brother Eric forming No Doubt, which would make her famous. Their 1995 release, Tragic Kingdom, was a massive breakthrough, spawning five singles including "Just a Girl" and "Don’t Speak," which hit number one on the U.S. charts. The album ended up selling over 16 million copies and received several Grammy nominations. Tragic Kingdom was followed by Return of Saturn and the 2001 album, Rock Steady, which was a critical and chart success. The singles "Hey Baby’"and "Underneath It All" won Grammys. In 2002, a collaboration with rap singer Eve on the track, "Let Me Blow Ya Mind," won a Grammy and heralded Stefani as a pop solo act to be reckoned with. Stefani’s 2004 debut solo album, Love.Angel.Music.Baby.
