http://www.rahmania.net/1) Research on ARR's music. Like Raaga analysis of some of his semi-classical numbers.
2) Rare chords that he has used in his music. (Many of his songs has 7th, 9th, sus4 chords)
3) Scintillating Back-Ground pieces.
4) Articles on him can be scanned (or) made in to PDF and can be made available to the world.
5) Good links about his music.
We need to have these information for the next future generations and aspiring music composers as well.
Cheers
