The Band

Yobrepus is an art-rock band from Oslo, Norway – founded in 2017, following the surprise signing of singer and songwriter Mats Jørgen Sivertsen's solo, bedroom project, «Blakc Mould». That album, which was produced by Leon Muraglia and released by Furuberget, was later described by Prog magazine as a mix of «Radioheadinspired sadcore», «trip-hop» and «quirky indie-folk». The much praised follow-up album «Mycelium Days» ventured into a more progressive territory, blending cinematic soundscapes, melancholy moods and heavy riffs.

The members are Mats Jørgen Sivertsen (vocals, guitars, keys), Vegard Weyergang Vartdal (vocals, synth, bass), Øyvind Rognerud (keys, guitars) and Paal Urdal (drums).


Blakc Mould was released on Furuberget 5 May 2017. The album is available on vinyl and digital platforms. 9 songs and 45 minutes of inventive indie art-rock. Produced by Leon Muraglia and mastered on all analogue equipment by Alf Håkan Åkesson in Sweden. You will receive a nice 180g vinyl edition as well as lossless digital files for the same price as the vinly will be in the shops.
