BANDUNG, Indonesia – About 40 people from the Islamic Defenders Front (FPI) and the Movement to Reform Islam (Garis) on Wednesday (June 20th) protested outside a Bandung radio station where a trio of Dangdut musical performers is scheduled to perform Saturday, local media reported.

The groups have called on local officials not to issue a permit for the performance, borrowing tactics recently used to stop a planned Jakarta performance by pop star Lady Gaga.

The protesters are demanding that members of the Trio Macan wear headscarves and sing religious songs if they perform at Cosmo Radio Bandung. Station director Mufti Muchtiar told The Jakarta Post he had asked the group to tone down its sexy outfits and "erotic dances".

"We have to prevent sinful acts from happening," The Post quoted protester Shohirin Ahmad Abdullah as saying. "Should this radio continue its plan to hold the concert, don't blame us for what's going to happen."

Dangdut originated 50 years ago from Indian film music and has absorbed many cultural influences since then. The wildly popular Indonesian song genre has grown increasingly raunchy in recent years.
