In descending order:
1. Theater People - Notice the trend, here? Patrick Hinds is definitely a “fan boy”, and it shows. His enthusiasm is part of why I enjoy his podcasts so much. The other reason I like them is because he prepares well. He also listens well, and in spite of how often he claims to be overly star-struck and nervous, his interviews always flow like friendly party conversation.
2. Pop Culture Happy Hour - Not exclusively theater, as they also discuss movies and TV.
3. Fresh Air - Most often the topics are political or “newsy”, but if a show or a performer are trending, Terry Gross will probably interview them. Gross is an amazing interviewer. Personally, I think it’s because she’s such a good listener, and is extremely well-prepared.
