VINYL FORMAT. Probot is the result of Dave Grohl recording an album's worth of bone-crushing metal at his home studio, then sending individual instrumental tracks to some of his favorite metal vocalists. With the help of Matt Sweeney (Zwan/Chavez), Grohl was able to hunt down most of his favorite singers -- and covered a lot of metal ground in the process. "There are some fast tracks?-the Cronos track (?Centuries Of Sin?) is old-school fast thrash metal," says Grohl. "The Lee Dorrian track (?Ice Cold Man?) is slow...with a proper doom-dirge to it, the Snake track (?Dictatorsaurus?) is reminiscent of old Voïvod, the Mike Dean track (?Access Babylon?) is old-school metal-hardcore crossover." Indeed many of the songs come off as a perfect match for the vocalist in mind. 11 tracks of heart-stopping METAL.
