European release on January 25, 2013, and the American release four days later on January 29, 2013. A companion EP, Vertikal II was released on September 20, 2013. 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 December 17, 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". In May 2014 the band curated the Beyond The Redshift festival in London, held across 3 venues with Cult Of Luna closing the festival with a headlining set at the Forum. New lineup and Mariner with Julie Christmas (2016-2018) 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. Founding guitarist Erik Olofsson told the band he wished to leave, and his final live performance with the band became 2014's Beyond the Redshift festival. Cult of Luna stated that while he is no longer a full-time member, "he is still a part of the Cult of Luna universe." He has been temporarily replaced by David Johansson of Kongh. On April 8, 2016, Cult of Luna released its seventh studio album titled Mariner — a collaborative release with the American vocalist Julie Christmas, formerly of Made Out of Babies and Battle of Mice. Contrasting the industrial- and city-focused Vertikal, Mariner explores themes relating to outer space. Before Mariner was officially released, Cult of Luna had already begun writing new music for their eighth studio album. Persson stated that the band already had the album's concept and theme in mind, stating: "The last few records have been this kind of continuous journey from the forest to the sky and I know where we're going after this." 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
