Pietro Martin Walker, known professionally as Petter, is an American singer-songwriter and actor, born on May 31, 2002, in São Paulo, Brazil. Blending his multicultural background and bilingual upbringing, Petter developed an early fascination with language, sound, and storytelling — elements that would later define his artistic identity.
Growing up between two cultures, Petter was exposed to a rich mix of musical influences ranging from Pop to alternative/rock/dance contemporary music. This eclectic foundation shaped his distinctive sound: emotional, cinematic, and deeply introspective. His songs often explore themes of self-discovery, love, solitude, fragility and vulnerability.
Petter began writing and recording music during his teenage years, using songwriting as both a creative outlet and a form of self-reflection. His early releases quickly gained attention for their lyrical honesty and atmospheric production, establishing him as one of the most promising voices of his generation. Beyond his musical career, Petter has also shown talent as an actor, participating in independent productions that highlight his ability to convey emotion both on screen and through song.
Since his debut, Petter has been recognized for his innovative approach to pop music — merging poetic lyricism with cinematic soundscapes. His work often blurs the boundaries between genres, weaving together elements of indie pop, alternative R&B, and electronic music.
Through his artistry, Petter continues to build a universe that is both intimate and expansive, inviting listeners into his world of intensity and reflection.
