"Nauka Charitram aka The Boat Performance" was the first ever Opera kind of composition set in Carnatic Classical music written by Saint Thyagaraja in 18th century. IMO, It's very difficult to explain this kind of music. So, I would advice you to go through the scans that I included to read the superb sleeve notes written by Christian Ledoux. 'Trichur Ramchandran', One of the greatest legends of Carnatic Classical music has performed this auspicious performance along with his wife 'Charumathi Ramachandran' and many revered Carnatic Musicians were superbly accompanied in this rare piece of Carnatic Opera. Heartily Recommended.
