A friend suggested Dan Carlin’s “Celts” podcast to me and I was immediately hooked. Every month or so I have a 6-hour drive (each way) so I put that time to good use and get educated by DC.
So far I have listened to the whole of “Celts”, 5 of the 6 WWI episodes and the recent “Supernova” which is a thoroughly enjoyable discussion of Japanese military and cultural history.
Whilst lengthy the material and discussion is rarely dry, and DC does an admirable job of presenting issues from competing perspectives. He does ‘take sides’ but not always the ‘good guys’. Perhaps his most valuable trait is the way in which he provides insight and context of the time.
Carlin also publishes another podcast which I believe is focused on current affairs, so I will give that a go also.
