The new soloist for this Satoyama thing, Asahi Tasaki:
Her piano skills are amazing. The part in the 25" mark is lovely.
She also sounds like she's had a very classical voice training. It sounds kind of weird in a pop song; I would love to hear her in a classical piece though. Wouldn't it be great to have a classical music release with this girl and other idols? Kaori Iida and Aichan would fit perfectly too
