Really, what do I need to tell you about PENNsound that will make you want to go there?  PENNsound is an mp3 audio archive hosted at the Universty of Pennsylvania of poets reading from their own work (for the most part).  There are recognizable names and writers you probably should have heard of, from Pound up to the present.  I recommend the Ted Berrigan reading of The Sonnets and Bruce Andrews, but hey, the list of authors is huge and growing, so you can listen to whomever you like.

What more needs to be said?  Go and listen to some poetry.
