This is the wicked, slacked-tuned intro riff to Slipknot’s "Psychosocial." It’s performed with brutality by my student, Colton, who’s more than likely the best student I’ve ever had in 10 years of teaching. At the time of this performance he had approximately 8 months of study which is very impressive. After 8 months of playing I believe I was still playing "Twinkle Twinkle Little Star" and "Mary Had A Little Lamb." Colton has no issues as a guitar student. He reads well, follows instruction closely, is an intense studier of music theory — and he avoids inferior playing tips, or tabs found at UltimateGuitar.com.
