Been listening to him for a while. His podcast title really doesn't do it justice. I always feel like a twat when I explain the epic scale and depth of his podcasts, then finally let them know the title

.
His Mongol series has been my favorite. Got me through a lot of long flights.
On a side note, check out 'History on Fire' by Daniele Bolelli. Also very good

. I'd check out his episodes on Custer's last stand. Similar level of detail, however with a strong Italian accent (which is better than it sounds - I find I concentrate a lot more as I'm constantly trying to understand him, which prevents me from drifting off if I become preoccupied).
