During its first two years, PLOC sought to foster students' creativity through work with recording techniques, sound editing, composition and musical improvisation. In this initial phase, the technical production of the music video "Pontes para o Passado" and the formation of the musical group "PLOC Imaginary Orchestra " stood out, which has already performed performances involving PLOC students. The year 2019 was marked by the beginning of the reapplication of Social Technology and the development of several works, including the launch of two music videos, the contribution to sound capture and construction of the sound design of the 13 episodes of the series "1 Pé de Banana Nanica" and participation in an audiovisual workshop with the team from Oitorama Filmes, from São Paulo. Despite the Covid-19 pandemic, in 2020, PLOC managed to maintain its training in an online format, focusing on adaptable activities to be carried out at home. The students actively participated in the sound construction within the audiovisual and in the production of electronic music, resulting in the creation of two audiovisual series and contributions to the sound capture and sound design of the "Tatatatu" series. The year 2021 marked the return to external activities, including the opening of a new reapplication class. Additionally, the students captured the sound of 5 short movies produced by LuCA Social Technology. In 2022, with the aim of addressing complementary content on the application of sound in the job market, two artistic collaborations were developed with guest workshops: Andrey May, addressing the creation of websites and digital sound platforms, and DJ Dolores, discussing identity sound for audiovisual productions.
