"Rattle That Lock" is the fourth solo studio album by English musician David Gilmour, released on 18 September 2015 via Columbia Records. The album's artwork was created by Dave Stansbie from The Creative Corporation under the direction of Aubrey Powell, who has collaborated with Gilmour and Pink Floyd since the late 1960s.
The album received generally positive reviews from critics and was commercially successful, becoming Gilmour's second solo album to reach number one on the UK Albums Chart. To promote the album, Gilmour embarked on the Rattle That Lock Tour during 2015 and 2016. A notable performance from this tour, held at the Amphitheatre of Pompeii, was recorded and released as the live album and video Live at Pompeii in 2017.
Rattle That Lock was recorded at David Gilmour's own recording studios. Co-producer Phil Manzanera noted that Gilmour had been developing the material for the album over a span of five years, although one piano piece on the album was recorded 18 years prior in Gilmour’s living room. Most of the recording took place at Medina Studio in Hove, with additional sessions at the Astoria houseboat studio. Both studios were also used for the final Pink Floyd album, The Endless River. Orchestra parts were recorded at AIR Studios in London, and the Liberty Choir was recorded in a South London church. The album was mixed at the Astoria studio, with mastering handled by James Guthrie and Joel Plante at das boot recording in Lake Tahoe, California.
The title track, "Rattle That Lock," was inspired by the SNCF jingle composed by Michaël Boumendil, which Gilmour recorded on his iPhone at Aix-en-Provence station. Boumendil initially thought Gilmour’s message might be a prank and did not return the call. The lyrics for the song were written by Gilmour's wife and collaborator, Polly Samson, drawing from themes in Book II of John Milton's Paradise Lost. The track features performances by Mica Paris, Louise Marshall, and the Liberty Choir.
Additionally, Gilmour's son Gabriel made his recording debut by performing piano on the song "In Any Tongue."
