KT Tunstall

With 2016's Kin, KT Tunstall began a trilogy of albums to examine spirit, body, and mind. She's just released the second installment, called Wax, which explores the body, and has an appropriately visceral, electric guitar-driven sound. Today, KT performs a set from the new record, plus some early hits, including "Suddenly I See," live in her hometown of Edinburgh. Host Talia Schlanger joins her there for a conversation about Scotland's disproportionately massive musical output, and KT shares about the first time her brother, who is deaf, was able to hear her music with a cochlear implant.
