On a strangely coincidental note (with all this talk about fusion and stuff), one of my (younger) relatives played this for me last weekend as he felt it "may perk my interest" - and it did it. Strangely I always thought one place where many of the 'melancholic' scales behind our ragas can really thrive in a symphony setting like this one. Of course Ilayaraja and others have already done this, but here is a Swedish "death metal" band Therion doing a piece with (their usual) symphonic setting where the scale should seem definitely "familiar" for many Indian ears:

Can you make out the Indian raga whose scale matches this one?
Warning: Since this is metal and I guess death metal - be prepared

! Although if you have heard and like some of the really rousing western pieces like say O Fortuna (Carl Orff), this is in that mould.
