Satoru Iguchi

Okay, that falsetto. The first time Satoru Iguchi's voice cracks open into that high, glassy register, I swear I sit up a little straighter, like the air in the room just got colder and cleaner. What gets me is the math of him: a kid from Ina out in the Nagano mountains who studies vocal music at Tokyo University of the Arts, and then the thing he makes is this jagged, art-school-meets-rock noise with King Gnu. That should not all fit in one person. And then he goes on the radio and instantly becomes the goofy older-brother type, no distance at all, which is a whole different guy from the otherworldly creature who sings. Keys, vocals, acting — he could easily be a jack-of-all-trades who's master of none, but somehow each one lands. Genuinely rare, and a little infuriating because of it.
