"Lesson #1 is that rock music is in the fighting spirit, not in the amperage of the guitars; indeed, some of the toughest rocking has come from all, or mostly acoustic bands; Elvis presented a primer lesson from the famous Sun sessions, with a simple blues song through the most famous faux false start in rock history; he and the boys start out all slow and bluesy, before stopping the band cold and calling it out like the hippest beat poet: 'Hold it fellas. That don't... move me. Let's get real, real gone for a change'. Then they did, let it loose, turned every bit of intensity in their beings into a jumping arrangement, much faster and more rhythmically nuanced a performance than the opening. Much of the intensity is in the fast and furious, but precisely laid out detail work; there is a strong sense of spontaneity and discovery, but what ultimately makes this a hall-of-fame performance is the vocal performance; Elvis doing tricks, making sudden octave wide jumps. "If you see my milkcow..." There is a charismatic determination of spirit that Nietzsche would no doubt have recognized as the will to power; when the King got through with it, it was no longer anything to do with a high calcium drink, but about the singer's assertion of his place in the universe."
