Sky Yen is the first album recorded by English musician Pete Shelley, recorded in March 1974 and released by his label Groovy Records in April 1980. It is Shelley's earliest known recording, and was created when he was in college. After developing an interest in electronic music, Shelley created a single electronic oscillator with an added potentiometer, and recorded the album on the device in his living room while utilising a two-track stereo recorder. The entirely electronic album is experimental in style, and emphasises oscillations and drone characteristics.
