Don Osvaldo

About

Don Osvaldo, an Argentine rock band formed in 2010 by Patricio Santos Fontanet, emerged from the ashes of Callejeros after its dissolution. Initially named Casi Justicia Social (CJS) in tribute to Callejeros' legacy, the band adopted the Don Osvaldo name in 2014 to honor the legendary musician Osvaldo Pugliese. The band made its debut at Club Banda Norte in Córdoba, performing both Callejeros hits and new material. They released their first studio album, Casi Justicia Social I, in 2015, followed by Casi Justicia Social II in 2019 and Flor de Ceibo in 2022. Notable tracks include “Tanto de todo,” “Suerte,” and “Flores por piedad.” The band has continued to build a strong presence in Argentina with a mix of old favorites and new hits, reflecting their evolution and ongoing influence in the rock scene.
