On this edition of The Arts Section, host Gary Zidek puts a spotlight on an elaborate speaker system that provides sound artists with the ability to create and present innovative work. The Dueling Critics, Kerry Reid and Jonathan Abarbanel, stop by to review the touring production of the Tony Award-winning musical HADESTOWN. Later in the show, Gary revisits his conversation with Academy Award-winning director Alex Gibney, where they discussed his documentary CITIZEN K. And we’ll learn all about a local music sharing platform.
