NOTE: The quality of the audio in these recordings is not really up to scratch, but since the content is so good we thought it worthwhile to publish them. You’ll find you barely notice the sound quality after 5 minutes (but if you’re finding the audio quality frustrating, give the discussion a miss as that’s where it’s worst!).
