Technical virtuosity has essentially zero appeal to me regarding music. If anything I listen to exemplifies a high technical proficiency, it's merely coincidental because I find the actual compositions themselves and the atmosphere that it produces to be sound.
Yeah I see what your saying... There's some stuff of Yngwie's music that are incredibly challenging to play but yet the song still sucks... so yes ultimatley song writing is key.
But what I was trying to say was that I believe being a proficient musician, not neccessarly a virtuoso, is important in metal music.... but everybody has their tastes and interests.
