Mike Keneally & Marco Minnemann - Evidence of Humanity (2010)

One bright morning, world-renowned drummer Marco Minnemann settled down behind the DW kit in his secluded hideaway, punched the record button, and proceeded to pound out an astounding 52-minute improvised solo. When it was finished, he christened it Normalizer 2 and offered it as a sort of gift to a handful of his favorite guitarists, relishing the prospect of each adding his own signature madness to the mix.
