Mark Goodwin pointed me in the direction of the rather splendid SoundCloud, and in particular the Air To Hear group. Mark and a number of other poets have been posting recordings to the group for a while now - have a listen to some of them. They're far from being straight readings of poems.
Mark's own Frost And Stars was the first that I listened to, but there's loads of other good stuff. Some work better than others, but it's a really goods way of getting poetry out there.
