If Rage Against The Machine's Zack de la Rocha ever had to take a break, they could easily find an alternative. Denzel Curry would fit Zack de la Rocha's role perfectly if anything happened to his vocal cords. Kind of like cheerleading, you always need to pick the alternatives if someone else is unable to cheer. The alternatives are the backup for when they need to fill in when needed. God forbid anything were to happen to Zack de la Rocha's vocal cords, they're not as screwed. An American Rapper who goes by the name of Denzel Curry sure can carry a note just like Zack. There isn't that big of a difference between Zack and Denzel's vocals while covering "Bulls On Parade" above. If Rage Against The Machine ever needed someone to cover Zack it would be a wise decision to go with Denzel Curry. Because let's face it, we would prefer Zack's vocals but wouldn't complain if we heard someone who sounds almost like him.
