A friend of mine at Stanford is a serious organist and is one of a handful of students on campus who has permission to use Memorial Church as his practice room. I went after hours to watch him play and take some photos. The light was beautiful with only the ornate instrument lit up and the rest of the cathedral in gloomy darkness, a perfect complement to the haunting tones of the organ.
