A concert performance using a very rare Luthéal piano. The composer/improviser writes: “Visual interlocking symmetries and geometric shapes are transferred to the audible world of rhythm and counterpoint, with the spirit and energy of jazz, improvisation and folk music always at the heart of the performance. The piece contains a sequence of 52 closely linked pentatonic scales. Each scale has two pre-established areas in which ideas for improvisations can be explored and developed, and because the piece is continuous, the player and listeners take part in a journey that lasts about one hour.” (Two later versions performed by another pianist and a nine-piece a cappella choir can be heard on Emanem 5015.) 62 minutes.
