99 metal singers sing '99 Bottles of Beer' for dog charity

Ninety-nine metal artists have banded together to sing '99 Bottles of Beer on the Wall', a 23-minute song aimed to help dog charity. The collaboration was the brainchild of Scour guitarist Derek Engemann and bassist John Jarvis, as well as Gruesome bassist Robin Mazen, all under the moniker The Boozehoundz. They recruited the likes of their Scour bandmate Philip Anselmo (Pantera, Down), Kirk Windstein (Crowbar, Down), Bill Kelliher (Mastodon), Gary Holt (Slayer, Exodus), Brendon Small (Dethklok, Galaktikon), Derrick Green (Sepultura), Mark “Barney” Greenway (Napalm Death), Mike “XCIX” Williams (EyeHateGod), Chuck Billy (Testament), and dozens more to each sing a line from the traditional drinking song. Proceeds benefit Old Dog Haven, which helps provide foster care for older dogs.
