From the very first note, Norway's Jon Balke proposes a new sonic dimension with Skrifum, continuing a line of inquiry begun with Warp (2016) and Discourses (2020), solo piano albums that also processed the acoustic environment in which the music was heard. Skrifum (the Icelandic word for "write") takes things a step further. With the aid of electronic audio tool Spektrafon (which he helped develop), Balke is now able to directly manipulate ambient audio sound from the piano while playing - pulling out frequencies and sustaining them as chords of harmonics.
