Following up last week’s Rare Frequency podcast with Hiroshi Kumakiri and Jessica Rylan (disquiet.com), the duo switched handmade instruments for a second part of their live performance (MP3). As might be imagined, they have less initial comfort with each other’s tools. The opening noises are just that: tentative and sloppy, in an experimental, finding-your-boundaries, self-orienting sorta way. But as time passes, melodic playfulness and dramatic flair arrive, as does a back’n’forth that suggests two robots (from different manufacturers, if not different planets) on a first date.
