Someone who may not still be part of hexbear read out each of the chapters, we did try to have a group to help comrades get through theory by recording our own audiobooks, but organization is hard.

I listened to it, it's how I read the book. I seriously doubt it's still up though, it was on a temporary file site (blanking on the name)

Someone did a whole scan of "This Soviet World" and I think someone made an audio read of that as well. That might be what you're thinking of?
