Great Unknowns Showcase

This week's edition of All Songs Considered is full of surprises: great music from bands we'd never heard of before. They're not the easiest names to search for online: AU, Bell, Okay are a few of them. But they're all making inspired, richly diverse and beautifully produced albums. Hear the art-folk group Bowerbirds, Russian-born singer Olga Bell, the pop trio Try Me Bicycle (from our 'Second Stage' series) and more.
