One of my resolutions this year is to try to cut down on the carbon I spend on music. Notwithstanding my purchase of the In Rainbows discbox, I’ve amassed an awful number of discs of metallized plastic in barely-recyclable containers. (I say “barely” because K. got me a pencil for Christmas made out of old CD boxes, and a pen from dead car parts. But there’s only so many pencils the world can use.)
