Sestra Kuya (Si Golraine and Gerry Gonzales) is a multidisciplinary artist duo that connects spirit, science, and art. In 2025, they invented and engineered a process that transmits fluctuating electrical voltage applied to titanium sheets - turning color into soundscapes. Together, they make energy both visible and audible.
