Circa 2004 Southern Lord's brother in metal Dave Grohl told the label about some metal songs he had written and recorded with the dream of getting some of his favorite metal vocalists from the' 80s to put their pipes on. The instrumentals they heard were legit bangers and Southern Lord could not wait to hear the result of what this insanely sick project would manifest itself as. Probot was that result and the eponymous album under the moniker is absolutely one of the favorite releases the label ever had the honor of being involved with. Grohl wrote, recorded and played most instruments on all tracks while heavy metal's most upper crust like Cronos, Max Cavalera, Lemmy, Mike Dean, Kurt Brecht, Lee Dorrian, Wino, Tom G. Warrior, Snake, Eric Wagner and King Diamond burned their vocals onto these raging tracks! Soundgarden's Kim Thayil also appears on a few cuts.
