Universal Music Japan has just released a preview of the PV for band GReeeeN's new single, "Hana Uta", due out June 22nd!

GReeeeN, who never show their faces in order to keep from interfering with their outside careers, are represented in the video by a band of young men, and the preview shows the members practicing their instruments at school. Instead of closing the windows to the room, they decide to leave them open so everyone will hear their song.

The song itself is a fun summer rock song about life and being yourself.

Check out the preview below!
