An unexpected side effect of building a heavily-insulated darkroom in an outbuilding is that I can turn the music up LOUD and it's still barely audible outside so it doesn't annoy the neighbours or my wife :-)
Normally the radio is tuned to either Planet Rock or BBC Radio 3. Looking forward to Proms season starting in a few days time. If it's CDs then I tend to favour nice long symphonies, Mahler a particular favourite, or prog rock concept albums. Something to accompany a nice long lith printing session.
