Brilliant flute-led instrumental, which I find quite progressive rock, more than latin, that's what the changing tempo, the Ian Andersonesque-KingCrimsonian lead instrument, some kind of thick chord changes suggest me. Feels like a mèlange of styles and genres that would find a proper home in certain sophisticated music that was made in the seventies, and it doesn't seem unworthy of it.
Sounds right for a film. Very nice.
