Kyleaux (born Santi Layosa) is a 17-year-old Filipino singer, songwriter, and music producer based in Metro Manila. Known for his signature blend of contemporary R&B, soul, alternative rap, and early-2000s hip-hop, Kyleaux has emerged as a frontrunner in the next generation of Pinoy rhythm and blues. He is a prominent member of the independent creative collective 25hearts.

Kyleaux’s musical journey began at age 12, teaching himself drums, bass, and keyboard before diving into digital audio production. He acts as his own primary producer, crafting nostalgic, loop-heavy soundscapes that serve as a sonic canvas for his raw, coming-of-age lyricism.

He first caught the attention of the underground scene with collaborative tracks like “Gusto Kita” (with k1ko). He broke into the mainstream consciousness with viral, high-streaming singles like “I Don’t Wanna Lose (Palagi)”, “Selfish”, and “Ulan”—the latter demonstrating his seamless ability to weave Tagalog and English into smooth, melodic hooks.

In 2026, his rapid ascent was solidified when Rolling Stone Philippines named him one of the “Filipino Musicians to Watch,” praising his self-sufficiency and authentic, diary-like songwriting. Internationally, his talent was recognized by Jaded’s annual editorial program, The Good List. Driven by a desire to capture the exact emotions of his youth, Kyleaux continues to reshape the boundaries of the independent Filipino music landscape.
