Watch the Tap-A-Kirk online guitar lesson by Chris Buono from 50 Metal Guitar Licks You MUST Know

The art of tapping is no stranger to the world of metal, and there's been some insane moments of two-handed mastery put forth for the guitar world to gush over. But, out of all them, none have been heard more than Kirk Hammett's energetic run in the ending section of the groundbreaking Metallica track "One" from the brutal... And Justice For All album. This lick tames the stallion like passsage by transforming it into a basic Van Halen-esque triplet-based run, while still retaining the multiple tonalities Kirk superimposed over all static Em riffing. The closing features some clever double grace note movements that glide down the neck to a solid resolution.
