Strings at 2:38 are used in Orbital's Chime, reversed, slowed down, converted to mono, and delay added as well. Orbital themselves have always said that they sampled the lead synth and FX used in Chime from one of their father's easy listening records, but they were never able to reveal where they sampled it from because of copyright issues. This means that the intro melodies in Chime could also have come from a different track on the Sleepy Shores album. This is a (bad) recreation of the sampling done in Chime - https://clyp.it/1ydb...b7b7c9bf931135d
