Sergio Martinez (SirGPR) is a Puerto Rican music producer, lyricist, and artist from Ponce, Puerto Rico, where rhythm lives in every street. He began playing at six and grew up exploring sounds from reggae and rock to orchestral and electronic music.
After serving 20 years in the U.S. Air Force as a Weapons Troop and leader, Sergio returned to his first love, music. What he learned traveling the world shaped his sound: grounded in Latin roots, blended with global rhythms, and always guided by love, respect, and kindness.
Through SirGPR Music Studio, Sergio creates clean, soulful music with depth and intention. Each song carries emotion, storytelling, and a touch of Puerto Rican percussion—his signature.
Every visual story is brought to life by Alysia Martinez, Creative Director at SirGPR, combining art and technology to reflect the message behind each lyric.
