A challenge in making a film about a complicated discussion is avoiding it becoming just a lot of talk. In our case - not just shooting artists saying smart things, but actually giving you as viewers a sense of what their creative work is about. That is what we focused on while in Tokyo.

We met the talented brothers Takafumi Tsuchiya and Yasuhiko Fukuzono. (Yes, I know that they have different last names. But that's another story.) Yasuhiko makes beautiful, fragile electronica music under the name aus. His older brother Takafumi is a visual artist and, among other things, the man behind the brilliant music video for Apoptosis by Caelum.

When they perform together, Takafumi creates visuals that are synchronised with Yasuhiko's music. We watched the brothers rehearse in the studio, and got to see a fascinating marriage between art forms.

Later, we hooked up with director Makoto Yabuki. Yabuki is one of those creators that refuse to see any conflict between being an independent artist and doing advertising. During the day we followed him, he had a meeting about a video commercial and then went off to get some footage for one of his abstract art films.

We also shot rockers in Yoyogi Park, ate at a rotating sushi bar and bar-hopped in the notorious Golden Gai district. Not least, we interviewed the Yamaha crew behind the revolutionizing Vocaloid software. More about that later.
