Katatonia guitarist Anders Nyström's (aka Blakkheim) sideproject Diabloical Masquerade has entered Studio Castillo in Stockholm with engineer David Castillo to begin work on the band's fifth album, tentatively due out early next year on Avantgarde Music. The music is said to be a cross between the bands last two albums or, in other words, "lots of horror, weirdness and METAL!"
