Gwen Stefani’s still just a (rich) girl in her first solo outing – an up-tempo extravaganza full of club-style hooks and New Wave-inspired sounds.

The thirtysomething lead singer of No Doubt has created a lush and trashy party album that’s sometimes spotty but nearly always fun. A far cry from her No Doubt persona of ska-rock ingenue, she’s crowned herself quirky heir apparent of Prince and Madonna.

Don’t expect autobiographical confessions on this album. Stefani’s working overtime to make something as stylish and sleek as it is shallow. Only a duet with Andre 3000, with material from a speech by Martin Luther King Jr., hints the world has larger concerns than hitting the dance floor or getting it on.

She doesn’t quite pull off the ghetto chic of her duet with Eve, “Hollaback Girl,” but she shines when she serenades on the ’80s-inspired track “Serious.”

Nine producers, including all-stars The Neptunes and Dr. Dre, make appearances on the 12 tracks. It’s surprising, then, that bandmate Tony Kanal emerges the best of the producing team.

There’s no doubt style surmounts substance on L.A.M.B. But that’s not so horrible.
