No Doubt became superstars by mining diverse strains of '80s music. High-stepping groove merchants Fishbone and 2 Tone icons Madness inform the band's horn-peppered ska-punk; the New Wave of the Go-Go's peeks through No Doubt's kicky tempos and sun-kissed guitar licks. Gwen Stefani's coquettish vocals and colourful stage presence nod to Debbie Harry's unflappable cool and Cyndi Lauper's exuberance.
