Really? Radio City? Believe it! Props to Robin Miriam Carlsson—you can call her Robyn—the Swedish dance diva who successfully brought the hipsterati and the pop community together, a first since Annie hit our shores a few years back. The 31-year-old singer has been a longtime celebrity in her home country, but it's only been in the past five years that the singer's electro-pop sound has gradually taken over the U.S. If this inspired, sometimes quirky, high-octane double-encore set is an indicator, we'll being seeing her at MSG very soon. With Diamond Rings and Natalia Kills.
