an open-air psytrance gathering held at a farming club ground near the ancient city of anuradhapura, drawing its name and concept from the mythological figure of ravana and the idea of lemuria as a lost civilization connected to the island's deep past. the event spans full-on, hi-tech, psychedelic, and psy dub styles, with a lineup drawn largely from local and regional artists.
the setting and framing reflect a growing sri lankan psy scene reaching toward its own cultural reference points rather than importing a generic template. the goabase listing confirms this as a publicly promoted open-air event with a substantial roster of performers.
