Its all about economics. The poorest American is better off than the richest Indian.
Not Really. Almost anyone can afford concert tickets, atleast.
Besides, that is not the reason for not having gigs here. Metal isn't all that big in the eyes of the promoters/sponsors here. So there's no one to organize gigs. Since we had our first concert back in 2007, it has been steadily improving, though. Just needs a bit more time.
