Salon.com recently posted (OK, it was a whiiiiile ago) an article about Metal fandom in the tech-world of India.  Unfortunately, the author, Jason Overdorf, follows some of the same mistakes made by other media sources with limited knowledge of the genre (Dire Straits?  Metal?  HAHAHA).  Nonetheless, it is still a good read.  The author attributes the recent boom of modern underground metal in India to the availability and speed of the internet at engineering colleges.  Subsequently, this has not only increased fan support of the metal underground in India, but also the amount of Indian Metal bands getting recognized outside of India.
