Mastodon's newest album Emperor Of Sand came out one year ago and the band is celebrating the anniversary by releasing a mask of the main skeleton character on the cover. The mask isn't terrible looking, but for $60 I feel like they probably could've made it look a little less like a cheesy and fun Halloween mask.
Though hey, if this is your thing then go for it. You can grab yourself a mask right here and run around your apartment complex or neighborhood telling people to show themselves and show you what they're made of.
