440 sound collective was born through the free societies of Nosotros and the Botanical Garden of Petroupolis by people who actively participated in them.


440 Sound Collective is our effort to create a framework and reference metro to continue to deliver light and sound to events, performances, projections, concerts, speeches, and in general, in any event, by maintaining, upgrading and expanding the equipment of the movement and at the same time in an era of insecurity where self-identification and everyone versus all are launching as a one-way street, at a time when survival itself becomes a question of vehicle self-organization, collectivity, direct democracy processes and horizontal structures to take life into our own hands by creating our own relationships at work against traditional labor relations.
