I urge those of you who like good music, and aren't averse to electronica, to get hold of some Autechre tracks. They are the greatest electronica band ever, as far as I'm concerned, and I remembered this today as I was listening to their epic "Second Peng" on the bus. I consider several of their tracks to be the most beautiful and/or melancholic music ever made. They're easy to get hold of, too, as you can buy their entire back catalogue from Bleep. Go on, treat yourself.
