PHI UNO is the solo project of Luis Villalobos, a musician originally from Tonalá, Mexico, currently based in Chicago. His work explores sound as a space for expanded perception. Blending acoustic instrumentation, voice, repetition, live looping, and electronic processing, PHI UNO creates immersive soundscapes that move between stillness and motion, shadow and light, the grounded and the ethereal.

Drawing from experimental folk, drone, Mexican vocal traditions, and electro-acoustic exploration, the project uses texture, resonance, silence, and gradual transformation to develop a sonic language that moves between song and abstraction.

Since 2018, PHI UNO has evolved through distinct sonic and conceptual stages. Beginning as PHI, the project has developed through releases including Primigenio (2018), Aixcaquema (2025), Huella (2025), alongside live performances in Mexico and the United States, including an official showcase at SXSW 2019.

Now based in Chicago, PHI UNO continues to evolve through composition, improvisation, and live performance, connecting with venues, festivals, and collaborators interested in experimental and immersive approaches to sound.
