One of those "you have to listen for yourself to get it" albums. This is an immersive, disorienting work that touches many genres (black metal, prog, post-rock, Zorn-era Mike Patton-esque vocal screams) but is in its own entirely self-created darkened world. By the time the drums start up again 12 minutes into album highlight " Vasemman..." you are either all in with Oranssi Pazuzu or way out. Take the time to for this to get under your skin. It's a challenging mind-fuck but well worth it.
Favorite track: Vasemman Käden Hierarkia.
