'Twenty Thousand Hertz' investigates the role of audio professionals in our daily lives, from the engineering that ensures a car door closes with that reassuring finality to the Foley artists of Hollywood who synthesise the sounds of marine life using old kitchen equipment gathered at the pound shop.
The 'Art of Charm' podcast can be intimidating. Not just because it's the work of a lawyer called Jordan Harbinger. Not simply because Jordan has worked out how to weaponise all the many elements of the human personality that go to make up charisma in order to get people to listen to him, be impressed by him, or hire him.
The '30 for 30' strand started life as a series of behind-the-scenes docs for the sports channel ESPN. It has now spawned an equally fascinating series of podcasts. Like the films, these podcasts don't rely on access, the usual currency of sports journalism, and are strangely excited by stories that are complicated and require telling at length.
If, like me, you've never watched 'Game of Thrones', the podcast 'Binge Mode: 'Game of Thrones'' ought to be unlistenable. It isn't, thanks to the energy of the two expert presenters Mallory Rubin and Jason Concepcion, who have the wit to laugh at their own deep-dive devotion and are helped out by some smart editing.
For a wide-ranging look at literary matters, the 'Book Review Podcast' from the 'New York Times' is still one of the best. Presented by Pamela Paul, each episode has an interview with an author - recent guests have included Neil Gaiman and Sana Krasikov - plus a roundup of the uppers, downers and hanging-arounders on the U.S. bestsellers chart.
The packaging of Led Zeppelin's IV doesn't have the name of the band, doesn't have the name of the album: It's got a guy on the cover with a load of sticks on his back. This record didn't quite get to No. 1 in the United States - it went to No. 2 - but stayed on the charts for years and years and years.
'I Was There Too' talks to people who played non-starring roles in big movies. That means the likes of comedian Jimmy Pardo, who didn't make it to the finished 'Dreamgirls.' Still, he recalls that when an actor is put on hold for a movie, he gets paid for two weeks just for sitting at home waiting to be called.
