“Rivera”, by Curved Grooves, carried out between 2015 and 2016, focuses on a steady research on achieving different solutions to the clash between instrumental and electronic sounds: two worlds that appear to be distant as for composing, technical and prosodic approaches. It’s from this concept that the choice of material develops, ranging from the employment of urban noises and environmental samples to rarefied vocal tones and guitars, trying to conciliate the electronic sounds with a more human and concrete dimension. This research path brought a compositional form for which everything undertakes a gradual change. Therefore a development of the tracks led by inner, subtle, minimal variations which, little by little, overturn the initial bases in unexpected developments.
