Wake up dead vocal cover from Peace Sells...But Who's Buying?
Dave's vocals are very unique, but hard to match, I tried. 

Megadeth- Wake Up Dead vocal cover

A jokingly bad cover of Zombie, her vocals are hard for me to match so this is just for fun

The Cranberries- Zombie (intentionally bad) vocal cover

vocal cover of Nirvana's Negative Creep, lots of screaming and gravely noises all in the style of Kurt

Vocal cover of As I lay Dying's Distance is darkness. I know! That distance is darkness! One of my favorites from AILD

Enjoy all sorts of music, from thrash metal to Metalcore to Blues. Not the best, but I'll always upload some vocal covers
