As I understand Sepultura were trying to come to India for some time now. At last they seem to have confirmed their tour to India. The metal scene in India, which was never really down, is getting a face lift with the number of mainstream Rock/Metal acts wanting to come down for a concert. The biggest help was of course Iron Maiden coming down to India. And their revisit in 2008. And they all want to Rock in Bangalore.
And the word on the street is that Megadeth, one of the greatest Metal bands, may visit India too.
