A newcomer to recorded music, Kenneth Kirschner’s actually been working with experimental piano and electronics as long as college friend and collaborator Taylor Deupree (that is, for over a decade), and this is a captivating debut. Post_Piano functions on three levels: the first is a singular, rather noisy sample of a piano note, provided here in .aiff and MP3 formats; the second is a series of full-tonal-range compositions Kirschner composed from that sample (also in MP3); and third is Taylor Deupree’s digital experimentation with those compositions (actual CD tracks). So as Deupree’s Oval-ish treatments provide inspiration, you can use the .aiff file to craft your own versions. Beautiful music, and so much to do with it.
