Nothing like an elitist piano player for putting down electronic instruments and the rock genre in general.
Man so what if some of the stuff is not that technical to play. Just like if you isolate certain sections of bass playing that just are well pretty straightforward. Any way you come across as a musical snob but hey.
A keyboardists role in a metal band is generally support driven but as many have pointed out their soloing ability and intricate compositional pieces are at times brilliant. And it takes more then technique to play metal and rock and improvise. I mean I have played in small orchestras (bass guitar) for stage shows and here is this classically trained pianist who can sight read absolutely anything. But if you played a blues progression could absolutely not play a fucking solo to save her life. In fact the whole concept of "making something up" was terrifying for her.
And believe me this a common affliction of classically trained "musicians".
It cuts both ways.
