As the entire TIG rating system is vaguely based on the awesome amps from This is Spinal Tap, it is only fitting to mention that the seminal metal band will be reuniting this summer for the Live Earth concert in London. Indeed, if we needed an added bonus, there will be 10 minute film documenting Spinal Tap's revival (directed by Rob "Don't make me governor of California" Reiner).

Huzzah! I still love the excellent advice from the movie that can be applied to many situations: Certainly, in the topsy-turvy world of heavy rock, having a good solid piece of wood in your hand is often useful.

Rock!
