No One Can Ever Know is the third studio album by Scottish indie rock band The Twilight Sad, released by FatCat Records on 6 February 2012 in the UK, and a day later in the US. The album was produced by the band with assistance and advice from producer Andrew Weatherall, who helped the band in experimenting with analog synthesizers. No One Can Ever Know marks a shift in the band's "wall of sound" approach towards a darker, more industrial-influenced sound. Guitarist Andy MacFarlane describes the album's sound as "sparser... with a colder, slightly militant feel," influenced by artists such as Siouxsie and the Banshees, Can, Public Image Ltd, Fad Gadget, Cabaret Voltaire, Wire, Bauhaus, Magazine and D.A.F.

The Twilight Sad are a Scottish post-punk/indie rock band, comprising James Graham (vocals), Andy MacFarlane (guitar), Johnny Docherty (bass), Brendan Smith (keyboards) and Grant Hutchison (drums). They have released five studio albums, as well as several EPs, live recordings and singles. Their 2007 debut album, Fourteen Autumns & Fifteen Winters, drew widespread acclaim from critics, who noted Graham's thick Scottish accent and MacFarlane's dense sonic walls of shoegazing guitar and wheezing accordion. The Twilight Sad's notoriously loud live performances have been described as "completely ear-splitting", and the band toured for the album across Europe and the United States throughout 2007 and 2008. Sessions inspired by stripped-down and reworked live performances yielded the 2008 mini-album, Here, It Never Snowed. Afterwards It Did.
