The more I read interviews and articles by some of my favorite musicians the more I noticed how many of them were never classically trained, had lessons from a guitar guru or even bothered picking up a scale book. Take Kerry King from the band Slayer for example.This guy can practically break the sound barrier with his face-melting guitar solos and can write brutal riffs that would whip any audience into a frenzy. But he doesn't know shit about music theory!! He just knows what he likes and what he thinks his fans will like. Slayer has been around for almost 30 years so they must have found a "formula" that works. The article below goes a bit more in depth as to Kerry King's thoughts on music theory and also has some advice on economical fingering techniques.
