Attention drone fiends! Jörg Hiller AKA Konrad Sprenger re-convenes with Phillip Sollmann AKA Efdemin on Modular Organ System. Released via Hiller's own Choose Records label, it's the first document of the duo's installation piece where they created a self-built modular organ system from tubes, air pumps and vibrating reeds. The results are two deep penetrating, highly potent long-form drone works that sound absolutely colossal, and with a physicality that seems to vibrate every cell in the body. Pure sonic hypnosis.
