Kecak, one of the most popular dramatic dance forms performed for tourists on Bali, was developed cooperatively by Balinese artists and Western expatriates—most prominently I Wayan Limbak and Walter Spies—with the explicit purpose of meeting the tastes and expectations of a Western audience.
Driven by economic considerations, in the late 1960s kecak was standardized into the kecak ramayana known today. Kecak ramayana does not appeal to Balinese audiences in an artistic sense; instead it is perceived as a traditional way of generating income for the community. In contrast, kecak kreasi (or kecak kontemporer) has been developed by local choreographers since the 1970s.
With its use of both pre-1960 traditional elements and Western contemporary dance, kecak kreasi is rooted in the contemporary Balinese performing arts scene. These dances appeal primarily to a Balinese audience, showing that kecak as a genre can be more than income from tourism; in its contemporary form it is valued by Balinese audiences on the basis of its artistic value.
This according to “Performing kecak: A Balinese dance tradition between daily routine and creative art” by Kendra Stepputat (Yearbook for traditional music XLIV  pp. 49–70); this issue of Yearbook for traditional music, along with many others, is covered in our new RILM Abstracts of Music Literature with Full Text collection.
