I didn't really like the vocals, so I found this video https://www.youtube.com/watch?v=Jv_wQyZjXuo and decided to make a mod out of it. All credit goes to Rainbowmaker, I just slapped this into the game.

I don't know if the quality is the best thing, but this is literally like the only thing on the internet about a Donacdum instrumental, so I don't really have anything else to use.

Replaces donacdum's build up and assault (duh)
To install just throw it into your mod_overrides
