The point was to see if the song would be kept alive by file sharing, and was also apparently a statement against the conservative music industry, said keyboardist Anders Teglund in an interview.

It includes the three songs with which Cult of Luna intended to conclude Vertikal as well as a remix of "Vicarious Redemption" by Justin Broadrick.

On 17 December 2013, the band announced that they'd be taking a break of sorts for the foreseeable future stating "2013 have been a very active year for us and neither do we want or think it is good to continue in that pace" they also said "Sooner or later we will return in one form or another".

[6] During the recording sessions and supporting tours for Vertikal, Cult of Luna made two major lineup changes that weren't publicly addressed until 2016.

While recording the album in 2012, keyboardist Anders Teglund "left the band unexpectedly" and later was replaced by Kristian Karlsson of Pg Lost.

"[8] Johannes Persson stated in an interview in April 2016 that in 2013 he never talked about taking a break as previously reported, "what I wanted to say [...] is that we didn't have anything planned for the future" and added "for sure I never used the word hiatus".

[11] A live triple disc vinyl album from the show at La Gaîté Lyrique in Paris, which is the same as on the DVD in Years in a Day, was also released on 21 April 2017.

[13] At the end of 2018, Cult of Luna announced the beginning of recording sessions and posted teaser photos from the studio on band's social media throughout 2019.

On 20 March 2019 the band announced signing a deal with Metal Blade Records and first batch of European tour dates scheduled for autumn 2019.

[18] On 12 November 2020 Cult of Luna announced the release of a new EP titled The Raging River for 5 February 2021 through their own newly founded label Red Creek Recordings.

The band's songs are often long, slow, repetitive and crushing, heavy sections of distorted guitars often interspersed with orchestral interludes and extended, post-rock-esque forays.

That style, incorporating sections of "light and dark" into their music, has led to comparisons with contemporaries such as Isis (with whom they have toured), Callisto and Pelican, as well as the significantly older Neurosis.
