I stumbled across this today on YouTube; a video in which composer Nathan Johnson talks about scoring for the movie Looper, and how rather than start the process with a melody and work around it, he actually started with percussion.
And not just any type of percussion – he really thinks outside the box (or, studio) and uses completely unorthodox media; from bins, piping, DIY components, to even weapons. These then get recorded, mixed up, tweaked, sampled and arranged to create very powerful percussive rhythms that sound absolutely amazing.
I’ve not seen the movie yet, but it is on my to-watch list very soon. This really is a good example of creative parallel thinking to achieve a great result in a totally different way!
