I kept exploring Hiroshi Yoshimura a bit and I quickly found my favourite album of his. It's called Flora:
I can't stop listen to it. It's so beautiful and relaxing. There's an ethereal quality to the whole album, but maybe these two tracks in particular. Absolutely gorgeous. Asagao sounds a bit like Ennio Morricone going ambient.
Fantastic stress relieving music, which I think a lot of people could use right now.
