Kreng’s peculiar world of sound drew attention from the Norwegian record label Miasmah (now operating from Berlin). Labelboss Erik K. Skodvin approached him to release music from his soundtracks for theatre. This resulted in the critically acclaimed album’ L’Autopsie Phénoménale de Dieu’ (2009), followed by ‘Grimoire’ (2011), which earned him a reputation as one of the leading figures in the world of modern-classical-electronic composition. In 2012, the lavishly designed retrospective compilation box ‘Works For Abattoir Fermé 2007-2011’ was released. This collector’s item sold out in less than three weeks. In 2013 the 7″ vinyl ‘… And Then in The Morning’ was released by the label Sonic Pieces. ‘The Summoner’ (2015), his most personal record to date, was created around the Kübler-Ross model of the five stages of grief. Belgian sludgemetalband Amenra collaborated with him on one track. German musician and composer Nils Frahm mastered most of his albums. ‘To Yield’, a new album, has been announced for release in 2020.
