On their new album Free Yourself Up, Lake Street Dive stitches the most fun bits of pop, soul, disco, jazz and rock and roll into something all their own. The band’s four founders met as students at Boston’s New England Conservatory. They visit the Cafe to perform live and reminisce about touring in the early days when they stuffed a big bass into the front seat of a Subaru. They also tell stories about the big TV break they got from their fan Stephen Colbert, and what it’s like to celebrate the 4th of July at his house.
