Dear SS and 'simple' Carnatic music has nothing to do with caste, it may not be popular music but is the base for light and other kinds of music. Even folk music is commonly based on Nattai, kurinji ragams. IN Thanjavur district everyone from Police officer to farm worker has solid knowledge of carnatic music. Other e.g. are barbers who are excellent nadaswaram vidwans. In Kerala, even mapla muslims who claim arabic ancestory have excellent appreciation of carnatic. You may be aware of these facts, I am just reminding you. Only problem Dravidian atheists have is that 99% of carnatic music is devotional!
