i dont know which thread to pose/ask this question but here it goes:
during the late 80s - i think post 'agni natchatiram', IR began using a certain kind of polyphonic percussion/rhythm sometimes very very complex - often making one wonder as to how he even conjured up such complex patterns!
the percussion base for 'en uyire vaa' or 'ding dong dong - irandum ondrodu' or 'poongatru un per solla', or, 'subhalekha' (the polyphonic sounds in this track is a riot!
http://www.youtube.com/watch?v=Fu-waXRLXU8 - the interludes and NOT the prelude), or 'vayase tholi' (
http://www.youtube.com/watch?v=UXvFsQrwyM0 - the prelude percussion wow!)
since 1992-1993, his scores shifted away from the use of such polyphonic percussion arrangements and became more new-age style - the rock ballad like 'arumbum thalire' from chandralekha (1995) or the songs of poovarasan or an IV sasi film (forgot the name, it had the 'siru koottil chinna kokilam irandu' song)
if IR were to revert back to such percussion usage, the present day night club slam bang music crazy junta wud lap it all up for sure!
