This album consists of multitracked and studio-enhanced live, mostly improvisational, rock and electronic soundscapes, 2/3 of which has never been heard before.
True to form, in the now twenty-two-year-old life of Ulver, only one constant has remained, that being a forward-driving spirit that has moved this Norwegian-based collective forever through challenges and adventure anew, irrespective of reductive genre pigeonholing. Moreover, their latest voyage into the unknown is no different, marking another new chapter for an outfit characterised by wild and inspiring unpredictability, along with a fresh triumph for one of modern music’s most iconoclastic forces. 
The basis for "ATGCLVLSSCAP" – which the band has been working with under the moniker ‘12’ – arrives from recordings made at twelve different live shows that Ulver performed in February 2014, in which band the band vaulted into the deep end of an improvisatory approach to their performance. As Kristoffer Rygg, the prime mover of the band since its inception puts it wryly, "The tour was to be an experiment, kind of loose and scary for a band as ‘set in their ways’ as us."
