Robert’s father played flamenco guitar, and taught the skill to his son (Google it – he shreds). Kirk, meanwhile, found the rock/classical music interface through a less direct back door. Deep Purple guitarist Ritchie Blackmore, a huge influence on the young axeman, was noted for adding elements of classical and folk music to Purple and Rainbow’s palette, and even further into those waters was German wunderkind Michael Schenker, of Scorpions, UFO and his own Michael Schenker group.
Michael Schenker was – still is, actually – awesome. Had he been American, he would have beaten Eddie Van Halen to the punch of being the guitarist who changed everything. Technically gifted to an insane degree, he also came at it from a completely different angle than most rock’n’roll players at the time.
“When I started playing guitar, I’d look to people like Michael Schenker,” Kirk remembers. “The first composer I was drawn to was Strauss, and later on, I loved Bach, Beethoven, Mozart… German musicians have had a huge influence on me! They embrace a different type of scale – modal playing, which is a different scale based on the tones on a guitar. Schenker used that so effectively that it made him stand out, because everyone else was playing the same blues scales. But he was doing crazy arpeggios and things. My ears perked up, and I wanted to play like that, so I learned all the scales he was using.”
This rubbed off in a useful way. If you’re looking for a pro-tip on how to write and arrange riffs like Metallica, try this: write a riff, then another using the same notes in a different order. Repeat. This, Kirk says, though not studied or a hard and fast rule, but it is a classical method of dealing with music and melody.
“That’s how we’ve done things since [1984’s second album] Ride The Lightning,” Kirk reveals. “And that’s what classical composers have done for, like, 600 years! It’s not like we sit down and decide to do it that way – we just naturally started doing that when we were jamming. It was a way of making one riff into five riffs. In guitar circles it’s called Riff Mining.”
