Hey there, I only know a couple of songs from Kishi Bashi but the sound is pretty cool. His musical style is described below and I added a youtube link as well.
A lush array of looping and vocal/violin gymnastics... Kishi Bashi's debut full-length, 151a, is a bright and soaring avant-pop record written primarily on violin - Kishi Bashi's main instrument which has brought him to record and tour with the likes of Regina Spector, Sondre Lerche, Alexi Murdoch, of Montreal and more.
Kishi Bashi collaborated with of Montreal's Kevin Barnes on that band's new album, Paralytic Stalks. This last endeavor he credits with some of his most recent musical growth, acknowledging that Barnes pushed him to new heights of creativity, forcing him to explore a broader use of his primary instrument: the violin. This experimentation affected his loop-based live show and led to him write more of the new record with violin rather than piano or guitar, loosening him from the grip of habit and expanding his palette. Kishi Bashi uses Japanese singing as another of many layers, doing so without any trace of gimmickry, and achieving what, to Western ears, must sound like an expression of the ineffable.
