One of the best tracks off the new Sun Kil Moon is "Richard Ramirez Died Today of Natural Causes", which uses the death and previous exploits of Ramirez as a kicking off point for reflecting on age, mortality and news as a morbid marker of time.

This reminded me of two other great tracks based around serial killers:
Swans "Killing for Company". about Dennis Nilsen.
