The ATS® Sisters Collective is a project involving experienced ATS® dancers and teachers based in different European countries. All of them are FatChanceBellyDance® Sister Studios with their own ATS® troupes: Isabel De Lorenzo and Silvia Grassi are Carovana Tribale in Italy, Gudrun Herold directs Devadasi Caravan in Germany/France, and Philippa Moirai directs Moirai Tribal Belly Dance troupe, in the United Kingdom, and is a Tribal Pura International Sister Studio Continuing Education instructor. Four different mother tongues (Portuguese, Italian, English, and German) have been united by one common language: American Tribal Style® Belly Dance.
Since 2013 the ATS® Sisters Collective is been teaching and performing in many festivals in Europe (Roma Tribal Meeting, Hanover Tribal Festival, Bellyfusions Festival, Back to the Roots, etc.) and in the United States (ATS® Homecoming, ATS® Reunion). Ilhaam from Spain has been a member of the group since the beginning until 2017.
