On 15 October 2015, in an interview with website Steel for Brains, Ulver announced ATGCLVLSSCAP, a double album with over 80 minutes worth of material, consisting of multitracked and studio-enhanced live, mostly improvisational, rock and electronic soundscapes, 2/3 of which had never been heard before. Announcing further details on 28 October, the album was released on 22 January 2016 on Vinyl and CD formats via newly formed, London-based label House of Mythology. The basis for the album – which the band worked on under the moniker 12 – arrives from recordings made at twelve different live shows that Ulver performed in February 2014, in which the band played a set improvisatory "free rock" performances. Band member Daniel O'Sullivan took the multitrack recordings, sculpting and editing hours of material in his North London home, before Anders Møller, Kristoffer Rygg and Tore Ylwizaker got involved, completing the recordings at Subsonic Society and Oak Hill Studios, Oslo.
