The first question I asked myself when I received this record was quite obviously related to those unidentified tools on the cover artwork. What are thy? A full torture equipment of mad dentist? Primitive fireplace pokers? Mysterious tools for the cleaning of furnaces? Whatever they are, they supposedly landed on the table of the Poznan-based musicologist, sociologist and experimental drummer Adam Gobiewski, who wisely used them to forge one of the most extraordinary sets of really experimental percussive tracks that recently titillated my eardrums. Even though listeners, who cannot really understand this extreme experiments, could tag "Pool North" as the artifact of a sadistic sound artist, this output by Adam, which can not be considered a rhythmical exercise at all, is the exploration of a huge pack of remarkable percussive effects that quickly reaches the threshold of pure disturbances. In the seven tracks of the album, Adam melts over-amplified noises, somehow cacophonous drones, violent scrapes and other bizarre resounding strategies to squeeze intense listen experiences, that unavoidably stimulates the imagination. You could imagine the crazy attempt to hybridize a snare drum, a triangle, a trumpet, a doorbell and who knows what else on the clashing "Decay" or you could experience what a woodworm could feel when his humble abode got turned into toothpicks on the ironically titled track "Ellington Tradition" or you could even think that a hellish monster looking like an elephant seal is trying to enter in your house by forcing an old door and its rusty hinges, while listening to the scary "Manner and Timbre". Some ears could bleed, but it'll be worth.
