Escape Pod is, in my mind, the best Science Fiction Podcast out there. Basically, this guy buys the rights to produce audio short stories, of generally pretty darn good stories. Its free too, though you can donate.

I very highly recommend EP027: Union Dues – Iron Bars and the Glass Jaw – the first in a “series” of stories. Its about Super Heros too, and its easily one of my favorite stories of all time.

If you are unfamiliar with podcasting – well, don’t worry about it, its pretty straight forward. Go check the site out!
