"The Japanese rock band Kuzuboshi was formed in 2002. The band members have been coming up with ideas and practicing individually to write a new song, "Empty."
They have been working together for many years and have gained various experiences.
In this video, they used many multiple exposures, kind of hand-made analog effects with glass and water, etc.

This video theme is "From words to images and changes into music," and visualize the process of making a song."
