Podcasts have almost completely replaced the radio for occupying my driving time, and I often listen to podcasts on my daily walk. There are so many good podcasts to recommend – TED Radio Hour, Serial, The Tim Ferriss Show, Jeff Garlin’s By The Way.

But the most impressive and engrossing podcast I’ve encountered is Dan Carlin’s Hardcore History. Carlin goes deep and produces what are in essence audiobooks about each historical topic he takes on. But he delivers these amazingly well researched stories in a conversational tone that makes you feel like you’re sitting with a really interesting friend who knows everything about history AND who can tell a great tale.

His latest series on World War I is stunning for its detail and for its effectiveness in conveying the staggering tragedy of the first modern war. He doesn’t gloss over or minimize the stark, often shocking realities of what humans have done to each other throughout history, hence the name “Hardcore History”. His podcasts are not light entertainment. But they are remarkably good.

It’s easy to make a podcast now. You just need a microphone and a computer and you can talk your heart out and post it on iTunes. But what Carlin and the best podcasters create are works of art, carefully, painstakingly crafted with strong content and excellent production values.

Carlin goes deep into his subject, reading voluminously on the topic and laying out his narrative carefully before recording. What he delivers ends up sounding effortless. This level of commitment to quality content and production, though, makes a show like Hardcore History shine.

If you’ve got some time in the car ahead of you this holiday week, Hardcore History or any of the other podcasts I listed above are a great way to fill a few hours.
