Background Score - 65 is from

This piece is from Achamundu Achamundu. Composer - Karthik Raja. This is the theme instrumental piece as in the OST CD of the movie. I actually thought of watching the movie before putting this post and give my opinion on the background score of the movie, but I couldn't, I am yet to watch the movie. Anyways after Illayaraja, Karthik Raja is the only one who can write such orchestral pieces in Tamil Films.
