Almost by definition the track Small Hours from the One World album by John Martyn really should be experienced with the lights low.
Nicked from the web,
"One World was recorded at Woolwich Green Farm in Theale, Berkshire, which was owned by Chris Blackwell, using the Island records mobile studio. The majority of the recording was done at night as it included outside microphones trying to develop an external ambience and to prevent traffic etc disturbing the recording by day.
On the album, Small Hours was recorded at 3.00am in the morning at the edge of the lake next to the farm and captures the sound of the water lapping as well as the geese on the lake. Including Steve Winwood, it is a very moving piece with John's use of the echoplex giving the music a truly ethereal feel as the slow notes seemingly hang over the lake. Truly magical!"
