The latest project from Norman Cook, a.k.a. Fatboy Slim, comes with a cute backstory about a group of friends dropping by a Brighton, England studio for ’70s-era jam sessions with Cook and producer Simon Thornton. Though the timeline is fabricated, this mash of rock, soul, and rocksteady is distinctly collaborative. Iggy Pop’s deadpan delivery on “He’s Frank” sets the tone for an album that sometimes gets a little goofy, while the danceable “Toe Jam” pairs David Byrne with Dizzee Rascal (finally!). The lesser-known guests offer more misses than hits, but Emmy the Great shines on “Seattle,” a sunny, commercial-ready pop confection.
