Clamor from inside the earth as it’s being excavated, punctured, deconsecrated. Sputtering and whirring of failing machinery. Menacing layers of magnetic decay, iron turned to dust through the erosion of repetition. The amplified obscenity of the mundane, the indelicate hunger of a gravitational hollow. Separated from the comforts of familiarity by a thick, lusterless film. Signaler can be all of these things and more. A new album from Mattias Gustafsson’s long-running Altar of Flies project, hot on the heels of his Work Ethics CD on White Centipede, and his Inblick & Overblick cassettes from last year.
