Record Store Day 2019 saw, among a slew of other cool releases, a brand new EP from High On Fire. The release contained a new instrumental called "Bat Salad," a cover of "Into The Crypts Of Rays" by Celtic Frost, and a cover of "Don't Bother Me" by Bad Brains. Keep in mind the below video is just a vinyl rip, but it still sounds pretty good! Bat Salad as a chunk of three songs also kicks ass because Matt Pike is really good at what he does, which should be obvious by now.
Don't feed the Discogs hawks for a copy of Bat Salad either – Rough Trade has a few copies available here.
