I liked the piece too. Not sure what the consensus is on marrying synths and classical guitar but you sometimes hear pieces like this covering modern tunes or where the CG is backed by a band/orchestration and I think this can make it accessible to some people who wouldn’t listen to solo classical guitar.
I started listening to metal too (nwobhm during my youth to blame) but was drawn to classical and flamenco guitar at the same time. And still am along with many other styles of music.
So hopefully you still can work in and enjoy both genres.
Personally I think there’s always been an interest in classical from HM guitarists. You guys with appreciation for heavy and rock guitar presumably know all this stuff but I mention it anyway.
The Metal Evolution documentaries have highlighted how the marriage of blues, rock n roll, amplification and then importantly, the bombast and intricacy of classical symphonic music (e.g. Holst Mars, Ride of the Valkyries etc) arguably created the early bands such as Black Sabbath.
In fact, their titular song from their 1st album came from them playing around with the riff from Holst Mars I believe.
I don’t know much about the US bands that also were in the pot at the same time like Iron Butterfly, Steppenwolfs etc but if you look at the 3 UK bands that were probably the starting point then you get:-
Deep Purple – Blackmore and Jon Lord’s Bach/Baroque influences
Black Sabbath – Symphonic influences
Led Zeppelin – no obvious classical (I think?) but very blues/folk oriented
So I think from this starting point, CG has typically been of interest to us metalheads or most of us at least! For example, Randy Rhoads (RIP) who played with Ozzy Osbourne was a keen classical guitarist and would have lessons in different cities/towns when they were on tour.
Rodrigo from the due Rodrigo y Gabriela also used to be in a metal band (not sure about Gabriela) and now they play on nylon strings although they are more of a crossover thing with Spanish/flamenco overtones I think. I’m sure a lot of you know this already.
Actually, I wonder if any professional players came from, or, have an interest in metal? I’d find it funny to find out if, say, John Williams used to listen to metal for instance. I doubt it in his case. But certainly he has expressed opinions on how CG players shouldn’t be held back from playing other styles such as strumming in an Irish band, or, playing in a crossover rock band…oh hang on a minute, he did that didn’t he
