If you plan a blindfold test for your know-it-all friends who pretend to identify everything experimental, subject them to this CD. There is no chance that they’ll guess the source used by Alfredo Costa Monteiro to bring out sounds that could be described as follows: polar wind, creaking knees, squeaking shoes, a bicycle seat that needs to be lubricated, drunk seagulls, echoing purrs, a walrus in love, the air current that precedes the arrival of a subway train, a hundred woodpeckers on cocaine, a violinist who put a finger in an electric socket and arcoes at 2000 km/h, ice skating on dying mice, horses running on crumbled concrete, chalk drawing on a blackboard, bionic chickens looking for seeds, water pressure in a malfunctioning toilet, amplified gas bubbles in a soda can while a car passes by, flanged Moto GP races. Make no mistake: this is only 30% of what you get in “Allotropie”, recorded testimony of “Concatenaciò”, a 2005 installation presented in Barcelona. The album is also another splendid example of what a real artist does, because he gives life to ideas rather than copying them. Costa Monteiro, whose creativity can’t probably be fully appreciated if you never saw him perform live, is one of those perennially ebullient brains that find a way to make music out of an instrument, a circuit or sheer inert matter, the results being always the same, namely refreshingly mind-bending sonic materials that are unluckily heard by a few hundred souls while they deserve a much wider attention. It’s great music, to be listened to while also getting energized from. That’s right, the source: different types of paper, without additional electronic treatment. Short and sharp. A genius.
