I recently listened to this, it was a pretty fun listen. He definitely gives a pro-bolshevik angle but he interviews a bunch of people who weren't, I think it gives a pretty good idea of the political situation and how it was rapidly changing at the time.

My favorite part is how completely pissed SRs were that the Bolsheviks were just like "Hey that's a nice land redistribution policy you have there, we're just going to decree that now that we're in charge."
