Kirk Hammett

The concept of clearing one's mind before performing a task so that it is consumed by nothing but that task, yet is open at the same time to anything that might happen - that concept can be applied to playing guitar, and it's enormously helpful for improvising.

I've always been attracted to the darker things in life. I was never one to go for light, airy stuff, even as a child. My whole aesthetic has always been one of the darker side. That rings true also in my tastes in music. It's just always something I've gravitated to naturally.
