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.

Guitarist Andy MacFarlane describes the album's sound as "sparser... with a colder, slightly militant feel,"[2] 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 band released a new song, the album's closing track "Kill It in the Morning", for free on their new website and SoundCloud page on 21 September 2011.

[6] Although the song was not released as a single, a music video was produced for "Dead City", directed by frequent collaborator Nicola Collins, and premiered online in April 2012.

The Twilight Sad's supporting musician at the time, Martin Doherty, also stated that "the band who make the same record over and over don't have a very long career...

[9] The Twilight Sad also borrowed vintage analog synthesizers from producer Ben Hillier and Tape Studios in Edinburgh, which provide the core sounds on No One Can Ever Know.

[13] In an early preview album review, online website The Blue Walrus noted comparisons to Manic Street Preachers' The Holy Bible and Nine Inch Nails' The Downward Spiral, and finalised that "Some people may think that they know what to expect with a new Twilight Sad record, but if you thought you knew this band, you're in for the shock of your life.

"[19] Dusted magazine wrote in a similarly positive review, "The band that used to build shimmering, gorgeous, barely moving walls of tone is in a hurry to get on now, pushing post-punk style through dystopian, jittery landscapes of romantic disconnection.

The EP features a new song titled "Idiots" as well as alternate versions of tracks from the album, plus the B-sides "Untitled #67" and "A Million Ignorants".

The EP was made available as a digital download included with all orders from the band's webstore, and also as a special handmade CD-R inside a custom-printed cardboard sleeve.
