The first proper “album” from the dark ambient duo Grey Columns came along quietly in the middle of last month. I put the scare quotes in because, well, it’s only about 19 minutes long, which society has led us to believe doesn’t fit the description of an album. But it does fit the description in that these four tracks can’t be separated from one another. You have to take it in one long, slow gulp rather than just in piecemeal form. There’s also a true sense of purpose in how this collection is constructed. They move us with ease between the four movements of this album, sliding us into one grumbling, scratching, echoing room before we realize we’ve left the room we were just in. It’s masterful, beautiful, and the right kind of unnerving.
