With Skrifum, Jon Balke continues his exploration of solo piano, begun with Warp and Discourses. Thanks to the Spektrafon, an electronic audio tool he helped develop, he manipulates the ambient sound of the piano in real time, creating unexpected harmonics. "The sound of the Spektrafon spreads in such a way that it demands space," explains Balke, who plays here by focusing on each note and its position in a subtle and unprecedented soundscape.
