One of the most interesting radical improvisers of today's leftfield music, Alfredo Costa Monteiro has performed both as a soloist and as a member of duos and collectives (I Treni Inerti, Cremaster) playing accordeon, turntables and mixers in an unconventional way to say the least. Lately, though, his solo releases have shown an interest in digital manipulation and, my guess, more "composed" forms of mixing. "Épicycle" is a remarkable one-track work, clocking in at 37'37", where Costa Monteiro digitally alters samples of his own voice creating a frightening landscape. An ethereal drone is interrupted by abrupt granulated screams, as if black metal yells were processed by Peter Rehberg in the worst of his moods. The bathysphere of subdued frequencies is slashed and disfigured by layers of bestial laments, and words are slowed down to undeciphrable rumblings. If Henri Chopin's sound poems were turned into black mass summonings, they would probably sound like this. Play loud and never stop the madness.
