"Metallica’s Kirk Hammett and James Hetfield showcase two of the most important qualities that make up superb metal songwriter — air-tight rhythm playing and intricate yet memorable guitar leads. [...] From a guitar standpoint, much of Metallica’s influences come from early Iron Maiden and Judas Priest, and in many ways these acts walked so Metallica could run. There’s are a number of reasons as to why Metallica are the biggest metal band in the world, but for the most part it all comes down to their songs and more specifically Hetfield’s and Hammett’s approach to the guitar."
