Every year, Tremor tries to reinvent its presentation around community creation. One of the major achievements of the festival's collaborative efforts and ideas is the Som Sim Zero project, which is the result of a long relationship between the ondamarela collective and the Deaf Association of São Miguel that gains, this year, a brand new episode. This time, the two groups are playing alongside the Azorean percussion group Bora Lá Tocar.

ondamarela is a collective that conceives, develops and implements collaborative artistic projects. Above all, they are interested in the relationship between a specific place, a group of people in that place, and an artistic gesture built on sharing. They’ve worked with communities in Bragança, Ílhavo, Guimarães (European Capital of Culture 2012), La Valletta (European Capital of Culture 2018), Historic Villages of Portugal, among many other projects.

The São Miguel Deaf Association (ASISM) has the mission of developing and creating support structures for deaf citizens, guaranteeing their autonomy, individuality, their rights, and responses to their needs, acting in an integrated manner on topics like exclusion and encouraging the exercise of active citizenship. It promotes cultural, recreational and artistic activities, as well as intervening in the media to raise public awareness about the issue of deafness in all social aspects.

Originally formed in Ponta Delgada, São Miguel, in February 2007, Bora Lá Tocar began after a training session promoted by Associação Tradições, given by Paulo Tojeira, Mentor of the Tocándar – Marinha Grande percussion group project. Comprising more than 30 people, the percussionist collective is responsible for the construction of its own instruments and for the composition of the popular rhythmic imagery that guides its repertoire.
