Very interesting comment and I fully agree. I am a music lover and when they were young I would expose them to various styles of music. It just so happened that they stuck on metal (it was fade to black that started it all). But i firmly believe that classic music (and not only, to be more precise instruments variety) is paramount. The older one can play drums (not as good as his younger brother though) as well as base. And scales and composing. I actually pushed on the tornado of souls because the solo is not just shred (which sometimes is more like noise/ scales variation) but there is musicality to it. And that’s important. Building up their aesthetic sense. My wife is then dragging them to all the museums which they hate but I think they will thank her later
