I've been trying out
Atari Kousuke's music, and I love his most current song "Sora Ga Sora". He's a Japanese male solo artist, and his music genre is described as traditional, and maybe some pop, I dunno.
The only artist I would say is kinda similar to his music is alan, so if you like songs by alan, you might like Atari's music.
Sora Ga Sora PV:

I love the PV because it's so epic, and the song is just wonderfully arranged, and the use of traditional musical instruments make this song very good.
I remember I tried some of his songs in the past, but I didn't like them, but this song is just different, and it's my favourite song of his. I think he is very underrated, so I hope someone watches the new pv, and enjoys it. And I don't think he is that well-known, so I hope more people find out about him.
