'Neurochemie' is one of the most intriguing albums we've found on France's excellent Rotorelief label. It counts as part of ongoing research by Siegmar Fricke, a long-standing fixture of the European tape music scene who has collaborated with the likes of Maurizio Bianchi and Giancarlo Toniutti since 1985 (Siegmar Fricke started in 1981 making musique-concrete-experiments with magnetophones and shortwave-radio signals, recorded on various cassettes, followed by intense activities in the European tape-scene). His "audioclinical investigations" are characterized by shadowy techniques of "intermodulating, morphing particles and their mutual interaction in the stereophonic panorama", manifesting themselves in an unsettling array of dissonant dark ambient and uncategorised spectral electronics. There's a bunch more medical jargon attached to this release which you'd need a doctorate to understand, but essentially this is some of that real rare and genuinely ethereal electronic substance that you don't come across too often. Fans of Coil or Conrad Schnitzler should check in at the main desk and take a seat on the left. (Boomkat)
