Meh, the first kid's improvisation wasn't music, and the second kid did covers. Of course, it's damn impossible for the kids at 8, but creativity is different from skill. We'll have to see their composition skills.
Whatever. That comment reeks of elitist sentiment. The kid has forever to learn composing skills and the point of my posting it was just to show what an impressive talent he is seeing as how probably less than one in a million guitarists could ever be that good by age 8.
Seems to me that Sigz and I saw the same things in that comment. I actually turned off the first kid (the one who wasn't playing "Crazy Train") a third of the way through because nothing was happening, it was just wank.
There's a Devin Townsend video on YouTube where he basically goes over how easy it is to wank on guitar. Its hilarious.
