American Tribal Style® (or ATS®) looks old but is actually new, having been created by Carolena Nericcio (now Nericcio-Bohlman) in 1987.
ATS® movements are inspired by folkloric dances of the Middle East and India. Aesthetically ATS® is based on the richness of textiles and jewelry from North Africa and India. ATS® is a method of improvisational choreography, using a vocabulary of natural movements and cues allowing the dancers to communicate via gesture and eye contact when dancing together. (From the FatChanceBellyDance® website)
The foundation of ATS is primarily Middle Eastern dance. Moves may be modified from their traditional antecedents to fit in with the ATS group improv format in terms of cues, the number of beats taken up, and angle of the body, among other things
The music, movements and costume come together to create a rich and vibrant look that, despite appearances, doesn’t belong to any traditional culture. ATS is a pastiche of traditional elements, unified and embellished with modern creativity, assembled in the USA a mere 30 years ago and still developing.
