 First, though, it's a family group of four siblings called Infinity Song. From Detroit originally, when they moved to New York, they were performing on street corners and subway platforms, eventually catching the eye of Jay-Z, who signed them to his record label. Yep, that stuff still happens. This summer and fall, they're on tour, performing next month at Lollapalooza, and the new album is called Metamorphosis. From that, there's The Sunshine at Acoustic Cafe. If I told you where you'd be today...
