This phenomenon prompted Indian author Karan M to write:
"What’s funnier is that these “heavy” bands were passed down from generation to generation largely by earnest, bespectacled engineering students, so that, overnight, in grade nine, a certain segment of nerdy science kids began trading cassettes and analyzing the line-breaks in Metallica’s lyrics and headbanging to their homework. Why these bands in particular, I can’t say. What I do know is that tastes in India could remain static for years because rock music wasn’t viewed as a rejection of the previous generation, as it is in America: just listening to rock music was rebellion enough. Nor did we have the window into American cool that is now available through the internet. It’s amazing to think that our subcultures developed in such a scarcity of western music"
