One of the finest guitarists of this century, Metallica legend Kirk Hammett has posted a sincere photo of himself with St. Vincent on his official Instagram account.

Yesterday, Kirk Hammett has interviewed with St. Vincent. They have hung out altogether and talked about “riffs, band politics, and turning rage into music” at Cafe LaHaye.

Today, Kirk Hammett told his experiences with St. Vincent and said:

“Up now – my chat with @st_vincent 🎃⚡️🖤 hanging at @cafelahaye with the fine folks @rollingstone ・・・

Annie Clark, a.k.a. St. Vincent, gave up the violin so she could learn Metallica songs on the guitar. Now, she asks Kirk Hammett about riffs, band politics, and turning rage into music.

“We’re all just a bunch of cavemen, really, trying to find fucking cavemen riffs,” Hammett tells Clark. “But there’s a sophistication in your guitar playing that I just love.”
