So it's fortunate that Stefani's taste in collaborators tends toward the blue-chip: Dr. Dre, the Neptunes, Andre 3000, Dallas Austin, Nellee Hooper, and Jimmy Jam and Terry Lewis all earn producing and writing credits on Love, Angel. The album is a kaleidoscopic megapop picture show, full of freaky color and giddy texture: Opener "What You Waiting For?" is booming Eurotechno almost as beautiful as DJ Sammy's "Heaven," "Hollaback Girl" rides a bleacher-rocking Neptunes beat and "Luxurious" cribs the same schmoove Isley Brothers sample as Biggie Smalls' "Big Poppa." And as with the last couple of No Doubt records, the tender pop-rock confessionals are disarmingly affecting. In the TLC-ish "Cool," Stefani celebrates her unique friendship with her old lover, No Doubt bassist Tony Kanal: "Now you call me by my new last name," she sings over chiming synth-guitars. It's a moment rich with pop profundity.
