Southern India is known for Bharatanatyam dance (in Tamil Nandu) (you might have heard the term Classical Indian Dance) which follows a certain lineage/guru. The history of this dance is well documented easy to find more information if you so desire. Pongal is the celebration of the harvest which is observed in early to mid January each year.
During Pongal, the harvest festival, I was able to view some live performances in Chennai. I am also involved with photographing Bharatanatyam in Boulder, Colorado for over 10 years.
