Sing along with members of Pantera, Slayer, Mastodon, and 97 other metal musicians performing the folk standard "99 Bottles of Beer!" Listen here:
The project was put together by Scour's Derek Engemann and Nest's John Jarvis. All proceeds from the song will benefit the Old Dog Haven, a charity that helps old dogs find homes. Assembling the track literally took years.
"This has been an epically fun project involving the entire Metal scene, and even a few Ska bands! This project originally began back in 2013, but was brought back to life once we discovered Old Dog Haven," Engemann said on a GoFundMe page for the charity.
