This week, John and Stewart are joined by Erin Tonkon, a true twenty first century producer, engineer and mixer, who creates sounds that have all the visceral rawness of classic rock, only with a twist — expertise and immersion in new technology. Erin’s vast experience includes working as assistant to legendary rock producer Tony Visconti. She's worked with such artists as David Bowie, Kristeen Young, Esperanza Spalding, Daphne Guinness, The Foo Fighters, Fiona Silver and many more.
