Rust Never Sleeps is an album by Canadian singer-songwriter Neil Young and American band Crazy Horse. It was released on July 2, 1979, by Reprise Records. Most of the album was recorded live, then overdubbed in the studio. Young used the phrase “rust never sleeps” as a concept for his tour with Crazy Horse to avoid artistic complacency and try more progressive, theatrical approaches to performing live.

The bulk of the album was recorded live at San Francisco’s Boarding House and during the Neil Young/Crazy Horse tour in late 1978, with overdubs added later. Audience noise is removed as much as possible, although it is clearly audible at certain points, most noticeably on the opening and closing songs. The album is half acoustic and half electric, opening and closing with different versions of the same song: “Hey Hey, My My”.

“My My, Hey Hey (Out of the Blue)”, “Thrasher” and “Ride My Llama” were recorded live at the Boarding House in early 1978 and all of side two was recorded during the late 1978 tour. Two songs from the album were not recorded live: “Sail Away” was recorded without Crazy Horse during or after the Comes a Time recording sessions, and “Pocahontas” had been recorded solo around 1975.
