Reading Karl Marx is back in vogue. I have seen a number of news articles that have spotlighted the increased sales of Marxist literature. I would encourage every one to read Marx.
I can't think of anything better than a podcast dedicated to "Reading Karl Marx's Capital."
The podcast comes from David Harvey. You can find it here. Harvey has been teaching a class on reading Capital for decades. He knows his stuff. He also has an enjoyable speaking voice. He strays from a pure "textual" rendition of Capital and included a wide range of sophisticated techniques of analysis.
If you would like to "listen" to Capital on your own you can listen to a terrific version here.
