If you have liked the LULLATONES you sure will appreciate SORA, aka Takeshi Kurosawa, whose music is almost as delicate as the (other) japanese electronic band. Probably even more beautiful. So, listen to all these microbeats mixed with music-box-like harmonies, minimalism and (in the seventh track) also some jazz.
Tell me if you think about it. I find it mellow.
