Everything he touches is solid gold. The Neon Neon album is fantastic, especially when he takes the lead on tracks like I Told Her On Alderaan. And then nearly every Super Furry Animals album is fantastic, with the exception of Love Kraft. He doesn't write shit songs ever. His sense of melody and harmony is incredible and he has a fantastic sense of humour.
I'm gonna have a Gruff Rhys day, in honour of the man.
