This format of structured group improvisation was first developed by Carolena Nericcio-Bohlman, the founder of American Tribal Style.
[3] Sigil first studied with Antara Nepa (Julia Carrol), director of the Ottoman Traders located in Folsom, California.
Later she opened her own dance studio in Sacramento, California,[4] and was introduced to American Tribal Style by Shawna Rai.
Sigil used the basic improvisational format of American Tribal Style to develop a new vocabulary of movements, which evolved into ITS.
Elements associated with Tribal Fusion costuming are also commonly incorporated into ITS, such as antique multi-cultural jewelry, and permanent body adornment such as tattoos and piercings.
