A lovely little architectural radio show made at KALW in San Francisco. Shows are about 15 minutes long and concentrate on one unpredictable issue.
The episodes are rather well researched and produced, which might have something to do with their good fortune on Kickstarter .

Wayne, your Tudor tutor, invites a posse of authors, critics, builders, designers, and other architecture fiends to reflect on various topics related to perhaps the most functional of art forms.”
