Ferrum is a large-scale exploration of inharmonic timbres, oscillating between brutal grinding textures and intricate percussive singularities, created by digitally transforming recordings of various metallic objects. Susanne Kirchmayr’s new album takes a close personal look at the spectral richness of iron and other metals, in various shapes and sizes, recorded, processed, and arranged to a carefully curated selection of musical miniatures. Some of the results are an obvious nod to her Electric Indigo DJ alias, music that could be played on the dancefloor of an alien cargo ship, both highly familiar and foreign at the same time. Others offer almost steady-state like meditative qualities, vibrations from deep within, on a sub atomic level, full of light and motion on the tiniest possible scale. The limitation in material opens up a seemingly unlimited world of colors and rhythms, oscillating, resonating, and highly immersive. Mastered by Rashad Becker. Artwork by Tina Frank.
