Rock and roll took root in the Philippines decades ago, weaving into the country’s expansive domestic music ecosystem. This ecosystem nurtures iterations of the genre that carry the core hallmarks of the form while tying to longstanding local cultural patterns of music making and circulation. The sound bearing the title Sandali emerges from this ecosystem. It carries the formal classification of rock and roll, rooted in the Philippines’ long history of engaging with and reinterpreting global genre traditions for local audiences. Rock and roll as a global genre first spread across Southeast Asia in the mid-20th century, arriving in the Philippines earlier than many neighboring markets due to deep cultural and economic ties that facilitated the flow of recorded music across international borders. That early arrival meant rock and roll did not remain a foreign import for long.
