From orchestral works to installations, Peter Ablinger's oeuvre explores the differences between reality and our perception of reality. In '33–127' for electric guitar and CD, Ablinger confronts the rational, human division of sound into musical scales with the complex acoustical reality of any given moment - its "noise." In each of the 95 pieces that make up 33–127, these two realities come face to face again and again. In each piece, a scale descends, with gentle and unpredictable irregularities of both rhythm and pitch, from the top of the electric guitar's range to the bottom. The sound of the instrument is clean, clear, and precise. At some point in each of these tranquil, neutral scales - all but one of them, anyway - a cacophony of recorded street noise bursts in, which the guitar, now louder and rougher in tone, doubles, playing an orchestrated spectral analysis of this recorded noise.
