Peter Bjorn and John + Bachelorette

Half a decade on, it's a good bet that many people still have Peter Bjorn and John's whistly "Young Folks" stuck in their head. The Swedish band—a bit flatter live than on record—hopes to replace the song with something from its latest album, Gimme Some. Opening is the nifty Bachelorette, primarily the work of New Zealand artist Annabel Alpers, whose singing glides across electronic pulses with the chill of another synthetic instrument.
