I put up a link to an old Chills recording a while back. Here's some more recent stuff. There's the portion of a 2009 show that was broadcast on Radio New Zealand, plus a discussion on Hone Tuwhare with Martin Phillips and David Kilgour (including a song from each), and finally an interview and solo performance from earlier this year.
