I love browsing Poetry Archive - an archive of recordings of major poets reading their own work.
It's fascinating listening and I really like listening to Kathleen Jamie read - she's got a lovely voice and it's nice to have the affirmation of hearing a Scottish voice. Here she reads a beautiful poem called 'The Wishing Tree', it's really worth listening to.
I also love hearing Edwin Morgan read, his voice is very distinctive and once I've heard him read a poem I hear his voice in my head everytime I read that poem.
Unfortunately they don't have Kenneth White whom I heard at StAnza and whose voice sometimes pops into my head at any random point during the day!
