You can watch it on youtube if you are interested, it's broken up into 10 videos. Its not the same as watching it on the big screen, but at least you could see it. Absolutely worth it.
Balinese Monkey Chant:
Kecak (pronounced: /'ke.tʃak/, roughly "KEH-chahk", alternate spellings: Ketjak and Ketjack), a form of Balinese music drama, originated in the 1930s and is performed primarily by men. Also known as the Ramayana Monkey Chant, the piece, performed by a circle of 100 or more performers wearing checked cloth around their waists, percussively chanting "cak" and throwing up their arms, depicts a battle from the Ramayana where the monkey-like Vanara helped Prince Rama fight the evil King Ravana. However, Kecak has roots in sanghyang, a trance-inducing exorcism dance.
