Tonal journey across the Willamette

"I liked the tonal qualities of this recording. There is a constantly varying pattern of sound: the cars, trucks and buses never pass over in the same configuration so the tones will always combine differently. Each time I improvised this musical re-creation was also unique. The different patterns of sound could have gone on for eternity, but here I have just reimagined it twice."Hawthorne bridge, Portland reimagined by Philip Gibbs.
