Coming from India, I could tell you that 80% of the bands from here look to ape Western bands and suck at that. The rest kick some major ass and quite a few have an Indian Classical feel [either Hindustani or Carnatic] .
One of the best few that I could think of [ They are one heck of a live act and are to release their new album soon] http://www.myspace.com/infernalwrath
I guess you've heard Rudra [Singapore] and the other such bands that infuse Vedic chants etc, with a weird mix of BM and DM?
Although heavily ambitious, I'm hoping to fuse Carnatic Classical with Death Metal someday
