ats Jorgen Sivertsen began making music under the name Yobrepus (‘Superboy’ backwards) in 2006, but this is only their second album, following on from 2017’s Blakc Mould (sic). That debut sounded like the work of a band in search of a signature sound, dabbling in everything from Radioheadinspired sadcore to trip-hop and quirky indie-folk. Mycelium Days is similarly diverse in sound, but makes pronounced steps towards prog.
