==Carnatic music & Bharatnatyam== 
 Nilakana Sastri's book on Cholas (published in 1955) has section on their temple culture that was a precursor to Carnatic Music and Bharatanatyam. You should get it, if you already do not have it. Also the K. Indrapala's Evolution of an ethnic identity... puts it together as to how Chola Art forms directly lead to Bharatanatyam forms in sculptures in Sri Lanka. Indrapal quotes Nilakanta Sastri extensively.
