Recording of Jorge Rapp's Un Tiempo, Un Lugar. This piece was composed in the composer's studio and CICMAT. This work reflects dramatic moments of the Argentine history during the decade of the 70's. It was composed from electronic sounds and acoustic sounds of instrumental origin and social environment, processed in the laboratory of the CICMAT and in own studio. The acoustic sounds inhabit with melodic rhythmic impulses of electronic origin, fusing or contrasting between them. It consists of five sections, these interlace without a breath in between to a growing tension that declines towards the end.
