This is a raw, lo-fi cassette recording documenting a Balinese performance of the venerable Indonesian topeng mask dance. The propulsive gamelan overture that opens side A sounds really great through the murky tape fuzz, periodic mic feedback, and raucous crowd noise. For more info on Balinese topeng here's a good Jakarta Post article from 2001, specifically talking about the humor that's often a feature of performances in Bali these days, and also mentioning I Gusti Ngurah Windia who performs on this very tape.
