Reg this 'atypical' rAsA...
apdi onnu may not exist, because he had always been an 'envelop pusher' IMVHO :-)
What's possibly 'atypical' about NEPV (that is, strictly w.r.t. recent works of rAsA) is the quality of instrumentalists / instruments used in orchestration, thanks to the spending by Gautam.
Historically, that had been the key USP of rAsA. For e.g., in a yAnai-centric movie, he gave that 'nilavu nEram' (sung by PS, annai Or Alayam) -absolutely no connection to any of his prior works / handled genres etc.
Or, take that more popular 'nAnE nAnA' of AUA. Or, compare the odd 'thOLin mElE bAram illE' with the other songs of the same album.
avaru eppavumE appadiththAn, 'atypical' is 'typical' of him :-)
