A discreet but essential figure in the field of musical creation, Horacio Vaggione has been crafting an ambitious, precise and highly significant body of work for over the last fifty years, coupled with a demanding research activity. This disc offers four purely electroacoustic pieces which illustrate, each in their own way, this singular and fascinating grammar developed by Horacio Vaggione, a complex but fertile grammar which establishes a very special relationship between structure and texture, between matter and formula, to create a fascinating musical space, made up of polyphonies and metamorphoses.
