I'm having a tough time whittling it down to four centuries, or even four decades of the 20th Century. Beethoven or Queen? Copland or Johnny Cash? Dowling or Jerry Goldsmith? Billie Holiday or Stevie Wonder? I'll just bring four albums of bagpipes. Then if I get rescued people will understand. Check that; one album of bagpipes, one of Spanish guitar, one of Taiko drummers, and one with the Adagio for Strings on it. I have these, so I'll rip my own.
