I think this could be the heaviest (not necesarily the best or the nicest to listen to but I'm pretty sure it's the heaviest) song on Audiotool that isn't made externally or using samples. Let me know what you think!
*NOTE* All contributors are drums, toms, gun oneshots or the laugh samples. Everything else was made in Audiotool using only Audiotool's instruments.
This son of a bitch is killing my computer but I want to post a preview for you :)
