There are dozens of styles banging around the dark alleyway of “Rituals,” from the forthcoming Sea Levels from the Aussie-based artist Kloke. It starts as minimalist electronics — a heartbeat of percussion and the kind of crackling ambiance typically found on released by Wondering Sound faves Blackest Ever Black. But as it continues, it gets stranger, more restless. A mournful synth loops lazily in the background, lacing itself between the deep, insistent rhythm like the melodica in some dark dub song. Then it changes shape again — ripples of shimmering electronics make it feel like a mutant strain of techno, built for late nights at some Venutian dance club. It’s impossible to pin down — a constantly-moving, constantly-evolving shadow cast across a bedroom wall as the sun is beginning to set.
