They took it to Letterman, NPR, shared stages with Emmylou Harris and The National, headlined the Montreal Jazz Fest in front of 58,000 people, and did major tours across the U.S. and around the world. Their second album, Sleeping Operator was released in October, 2014 and received raving reviews. ‘‘Absolutely beautiful’’ (BBC6 Music).
