"From the most tenuous and crystalline, up to the real explosion, it is a fundamental disc, for its importance and originality but, especially, for its power of communication.” Sacred Theory of the Acoustic Space - Book I (2004) The work was recorded in real time according to the musicians stage performance, following the indications in the score, and without any processes of edition or assembling. The resulting spatial structures are the product of the development of timbrical, rhythms and/or dynamic curves produced by the performers, placed in fixed positions. The piece uses its own system of 3D notation, which includes a non-conventional musical conducting code. Martín Liut (La Nación) said, "With the ENS, Edelstein has found an "instrument" capable of making electro acoustic music, but with the traction of blood. The complex polyrhythmic textures and tímbres are the launch platform for the exploration of the space in three dimensions, an obsession that, now, Edelstein can record in a top format (5:1).” Current members Oscar Edelstein - Piano, Composition, Direction Axel Lastra – Piano & Keyboards Leonardo Salzano - Electric & Prepared Guitar Pablo Torterolo – Drums Mauro Zannoli – Keyboards & Electronic Processes Alfonso Ollúa - Electric Bass Guest musicians Deborah Claire Procter - Vocals Martin Proscia - Saxophone Past members Richard Arce - Electric Guitar Diego Romero Mascaró - Drums Gerónimo Carmona - Electric & Acoustic Bass Mario Castelli - Acoustic Piano Mariano Cura - Keyboards Matías Gonzalez Goytia - Drums Gonzalo Serrano - Electric & Acoustic Bass Pablo Siroti - Percussion Nicolás Varchausky - Electric Guitar References External links Acoustic Theatre LAPSO Ensamble Nacional del Sur Contemporary classical music ensembles Argentine composers Musical groups from Buenos Aires
