I had no idea who this guy was, but the album was recommended by a member of a fan group I follow (for the band Big Big Train). I gave it a listen on Amazon Music and was blown out of the water, and bought it immediately (even though it bears no resemblance to BBT).
The music reaches into the back of your brain, then down into your gut, and shakes you where you live. It's mystical and spiritual, contemplative and provocative. It seems simple, but every listen reveals new layers. It's the product of one mind, but seems to have come from multiple ways of thinking. It has the primitive power of a shaman's incantations, and the sophistication of an orbiting satellite that can see everything.
There is an effect you hear when siblings sing together. Sometimes, that effect is intensified and redoubled when one singer layers all the voices on a recording. I've never heard the technique used more effectively than on this album.
What's he singing about? I have no idea. Honestly, the music overpowers my ability to process language. It's visceral. Primeval. And yet gentle and relaxing, harmonic and resonant.
It's really something else. Go listen to it.
