Haha..my class is better...they dun really listen to rock..most people are into..eh....Mandopop stars like 5566. And they tell me stuff like..oh some member of 5566 plays the guitar but he only knows the basics (me too, u know??*rolls eyes) or some other member plays the piano (but like how well?)
And I've had lots of ppl telling me Yoshiki looks like some Satanic dunno wad when I play X videos..(though they go wah! when Yoshiki starts on his crazy running notes on the piano)
My friend played Gackt's Vanilla live video in class once and some ppl got real disgusted..(no taste lar...)
my secondary school class also like that. People sings avril and 5566. And once i said 5566 not nice in a crude way, people diss me on irc and stuff like that. Only like 4 of us listen to IM and Led Zepp and of cos X-japan, people say we cock lah this and that, and i did not know the other 3 fellas in class listen to these stuff until i left secondary school. Then we always try to show stuff new to them they will say wad metal/rock is noisy lah, not music and satanic. wad the hell...people jus dunno how to appreciate fine arts
musical theory enables you to Read music notation. It is useful if you intend to take your passion for music all the way. being a sessionist... professional level player..you will have a distinct advantage if you can sight read.
however.
can read music dooesnt mean you can play well. I know a few people who talk about ..augmented chords..diminished...formula for dunno what scales...etc..all the CHEEM stuff and pick up a guitar and play basic pentatonics.
theory is good. but you dun need it to become a good guitar player.
