The original studio recording, available on Bandcamp, Spotify, and all other major streaming services, was produced & arranged by The Resistance Company, and therefore has a punk band setup. That being said, listening to the original recording can be helpful for getting the basic musical idea. Decolonize will be a riff of sorts, similar to Which Side, that can be conducted and evolve in the moment, as opposed to having a hard form. However, if we need a default, we can default to the arrangement in the studio recording.
The drum break can function in the same way as all our other drum breaks: feel free to put whatever chant in there depending on the occasion. Of course, you always have the option to just do a two syllable minimalist chant as the recording does as well. Those syllables can also be played by our instruments while others chant.
