Perfecto "Perf" de Castro is a name that commands immediate respect in the Filipino music scene. Often referred to as the "Master of the 10-string guitar," he is a multi-awarded musician, producer, and educator whose influence spans from the peak of 90s Pinoy Rock to the intricate world of classical and flamenco guitar.

Perf de Castro first exploded into the public consciousness as the original lead guitarist of Rivermaya. His technical prowess and melodic sensibilities were pivotal in shaping the sound of their 1994 self-titled debut album. He is the architect behind the iconic guitar solos in hits like "214" and "Awit ng Kabataan." Even though he left the band early on to pursue other musical avenues, his "guitar hero" blueprint remained the standard for Filipino rock guitarists for decades. 

Beyond the fretboard, Perf is a highly sought-after producer and engineer. He played a massive role in the success of Francis Magalona’s Freeman album, bridge-building between the worlds of Rock and Pinoy Hip-Hop. Today, he is a prominent figure in the digital space. Through his YouTube channel, he shares unfiltered takes on the latest guitar tech, tutorials, high-fidelity performances that blend technical shredding with soulful expression.

"Perf is a rare breed of musician who can move a stadium with a distorted power chord and silence a theater with a nylon-stringed whisper."

He currently resides in the United States, continuing to perform, teach, and push the boundaries of what the guitar can do. Whether he’s holding a Fender Stratocaster or a custom 10-string classical, his playing remains unmistakably "Perf."
