“Cracks and Corrosion” is one of the most challenging and rewarding releases of 2009. It’s comprised of five works by Swedish composer Örjan Sandred, who deftly combines acoustic instrumentation with computerized sound modulation while avoiding the emotional sterility that characterizes much electronic music. Partly he achieves this through a range of organic sound textures that evoke various environmental phenomena—splintering ice, skittering leaves, even the “singing” of massed frogs near a lake in West Africa. His melodic and harmonic conception is similarly forward looking; angular and intricate, it keeps the listener intriguingly off balance, yet its inherent tension and drama keep one intellectually and emotionally engaged. There is also a surprising amount of warmth and lyricism, albeit expressed in non-traditional fashion. Each of the pieces is inspired by environmental phenomena and scored for a different instrumental combination—from a small chamber ensemble to a single guitar interacting with a computer—which adds to the disc’s variety of moods and textures. “Cracks and Corrosions” shows Sandred to be one of the most compelling voices on the alt classical scene. Highly recommended.
