@karschsp Mammoth WVH is a legend. The first album especially, where he totally "Dave Grohl'ed" the entire thing ala Foo Fighters' debut album.
I also saw him (and his band) open for Metallica, and he's just as incredible in a live setting.
(By the way, I just learned last month that Van Halen was originally called "Mammoth" before they were signed to Warner Bros.)
