The risk for a band like Sikth returning after nearly a decade away is obvious; after influencing an entire subgenre of metal, the sounds that they created back then are now far more commonplace, and churning out yet more of the same just isn’t going to cut it.
So to listen to Opacities is a rare treat – an example of a band who are more than happy to face their legacy head on, and then not just match it but better it. Any old chancer can grab an eight-string guitar and palm-mute the hell out of it, but how many bands could dream up the kind of complex vocal melodies and call and response lines as Justin Hill and Mikee Goodman do on the mind-boggling math of Philistine Philosophies?
How many bands would see that the tech boom that they spawned has swiftly run out of genuine ingenuity, and thus decide to incorporate the kind of doomy, arcane grandiosity that is usually associated with Opeth or Behemoth on the frankly jaw-dropping Days Are Dreamed?
Only Sikth spring to mind. Still visionary, still unique, still a good few steps ahead of the game. This is a comeback of the highest calibre, from what is a truly one-off band.
