Danish dance-hop duo Junior Senior is many things-frothy, frenetic, summery–but subtle isn’t one of them. When they say there’s “too much good stuff out there to ignore” on Hip Hop a Lula, they’re not kidding; they’ve got a kitchen-sink aesthetic that constantly jumps influences. Still, there’s an overall retro feeling to Hey Hey My My Yo Yo, their second full-length, that hearkens back to innocently sweet ’60s pop and the deep joy of Motown, helped by guest stars such as Cindy Wilson and Kate Pierson of the B-52’s and venerable girl group The Velvelettes. Who needs subtle when its opposite is so much fun?
