Although I think it fits really well with the subject matter, I think the strings bring a very grand feel to the film and give a sense of importance that wouldn't work with anything other than a Michelin Star subject. For my documentary I want to try and match the more down to earth nature of the kitchen I'm filming, which I will do using mainly solo piano. I think this will give a nice atmosphere without overblowing the context and importance of the subject matter. Two good examples of the vibe I want to go for are Philip Glass and Nils Frahm.
A classic piece that I would really like to try and capture some of the feel of is Terry Riley's 'In C', as it flows very nicely and would dip in and out very well.
