Contemporary music documentaries tend to fall into one of two categories: the track-by-track “making of” account, in support of a new album; and the “behind the scenes” artifact of a live concert tour (often in support of that new album).* Both can be fine in their own way, but ultimately they are there to plug product. The recent documentary “Coda”, featuring Ryuichi Sakamoto clearly bucks that trend.As a recording artist, Sakamoto is one of the most prolific composers of his era. As a performer, he has maintained a regular schedule of live concerts and collaborations. That is until he was diagnosed with cancer a few years ago, and was forced to temporarily abandon his work. Fortunately, he has come through that recent health scare, even completing a major film score for “The Revenant” before he had fully recovered.

“Coda” started out as an account of Sakamoto’s anti-nuclear activism, but ended up providing an insight into his creative process, an examination of the role of sound and music in film, and a discourse on the aesthetics of minimalism.

There are two images in the film which provide a link between the “craft” of the composer and the “art” inherent in any form of creativity. The first is a close-up of Sakamoto’s working tools – the pencils he uses to write out his scores. The second is a shot of some immaculate cooking utensils – arranged in a similar fashion to his perfectly sharpened pencils. This is someone for whom both process and form serve the purpose of creativity, and which combine to determine the artistic outcome of the resulting content.

As a regular soundtrack composer, Sakamoto has been likened to a film-maker, although he is neither director nor cinematographer. He has an acute sense of the use of sound (not just music) in film, and in fact for his most recent album, “Async”, Sakamoto invited film-makers to submit short films to accompanying each of the tracks. An astounding 675 films were considered for the competition.

Ever sensitive to his environment, it was perhaps no surprise that Sakamoto chose to change the music played at one of his favourite restaurants, rather than eat elsewhere. And ever the non-egoist, none of the tracks on his restaurant playlist was his own.

The forthcoming performance by Sakamoto and long-time collaborator Alva Noto at the Melbourne International Arts Festival promises to be something special.
