One is Rage Against the Machine. When I mentioned to Keven that I had seen Tom Morello play once and how iincredible it was to watch him, Kev spent ten minutes explaining to me the technique Tom uses for his unrivaled sound. I loved hearing him get excited about music. Since I can't remember his exact words, I'll just use the explanation from Wikipedia:
Critically acclaimed, he is said to use the guitar in a unique and imaginative way; rather than just plucking the strings, his maneuvers include toggling between two pickups - one on and one off - while rubbing his hands on the strings over the pickups (his signature vinyl scratch effect used in "Bulls on Parade"). He also uses techniques such as rapidly hitting a pencil on the strings ("Cochise", although he now emulates the sound by "baby-slapping" the strings), scraping an Allen wrench on the strings for a whole song ("People of the Sun") and even tapping the bridge with his audio jack cable ("Testify" and occasionally on "Bullet in the Head").
So, this video is for my son, Keven (who has never looked at my blog but - hey there's a first time for everything, right?)
