Shows how biased you are. That guy does EXACTLY what you've been bashing here - making weird sounds. But somehow because he plays in a band in the genre you like, he suddenly becomes "skilled".
The funny thing is that you can level rock music (which you obviously consider superior to electronical music) in just the same way. Which brilliant spectrum of emotions does a band like RATM enlighten upon the listener? You just have to face the fact that rock is very similar to any type of electronical music. They're both very one-dimensional genres, in which the way it sounds (the shape) is more important than what is actually played, the melodies/harmonies (the content). Ever tried playing a RATM riff on piano? If not I suggest you do, then you may realize how stupid it sounds if you look at it from a musical viewpoint.
I'm not trying to bash either rock or electronical music, I can enjoy both and listen to both often. I just find it really, really annoying that almost all rock fans think their genre is superior to electronical music, when in reality they are just about equal in musical quality.
I can give you dozens of names of guitar players who are way more underrated by the main public than Van Halen, but you probably wouldn't know them.

And comparing him to Kurt Cobain is just pointless, since he's a singer in the first place. He didn't become famous by just being a great guitar player like Van Halen.
Plus the fact that the shred type of music Van Halen makes just isn't accessible to the main crowd. Almost all big Van Halen fans are guitar players (I bet you are one too) who judge his music from a mere technical viewpoint.
Oh really? I just call it "wanking with a tremelo". He wrote pretty good riffs, but his solos are freaking terrible. And yet again very ironical that you like THIS GUY's nonmelodical sounds, which again come down to the same thing as the sounds in a lot of electronical music acts.
The phrase I put in bold all sums it up. This is just embarrassing really. Do some wikipedia research or something.
To sum it all up, you're just biased. And instead of acknowleding it, I expect you to come up with more biased arguments.
