Tremor Festival

Comissioned by Festival Tremor 2018, in the island of S. Miguel, Azores, we conceived, developed and presented the performance Som. Sim. Zero, with a local deaf and hear impaired organization and guest musicians.
In 2019, we are comissioned to work with last year’s friends plus the Escola de Música de Rabo de Peixe.

Som Sim Zero: In the street, the meeting

Last weekend, at the Tremor Festival, we presented another new creation by Som Sim Zero.
This time, a journey, on the street, with ASISM, the musicians who accompany us, Bora Lá Tocar and Back to Funk. This time, in addition to our wonderful Samuel Martins Coelho, we had with us the incredible Patrícia Costa, in costumes and props.
About the meeting, opening doors, time and invisible things, we surround the festival audience in a cloud of good things.
Thank you everyone, we leave here some beautiful photos of Vera Marmelo.

The meeting is revolutionary.

To let in.

Listening is revolutionary.

To participate.

Wanting to know is revolutionary.

To dance.

To draw a circle,

to bring together,

to discuss,

to laugh,

to touch




Silence is revolutionary

The sound.

Thinking is revolutionary.

The no.

The gesture is revolutionary.

To smile.


To draw a circle,

to bring together,

to discuss,

to laugh,

to touch

Many thanks to everyone who continues to carry out this incredible joint effort that is Tremor. And many thanks to everyone who helps us build Som Sim Zero, year after year. It continues to be a wonderful discovery, a beautiful learning experience, an immense pleasure.
This year, at Teatro Micaelense, it was very intense and we were all very happy.

Som Sim Zero at Rock in Rio – the documentary

The Galp Foundation has already published the documentary about the adventure of our Som Sim Zero concert at Rock in Rio 2023.
It is very beautiful and emotional, and served as a motto for us to meet again this month in Rabo de Peixe.
Have a look there:

Som Sim Zero in Rock in Rio Lisboa

Many people have come to film and record our rehearsals at Cine-Teatro Miramar, in Rabo de Peixe, S. Miguel Island, Azores and there have been many questions and many answers. We are very anxious!
