Julianno Sosa

​César Alejandro Pozos Martínez, known professionally as Julianno Sosa, is a Chilean urban artist born on August 8, 1998, in Puente Alto, Santiago. He began his musical journey at 16, crafting homemade recordings influenced by the emerging trap scene. In 2015, he partnered with fellow Puente Alto native Pablo Chill-E, forging both a musical collaboration and a strong friendship. At 18, Julianno Sosa moved to New York City, pausing his music career to pursue financial opportunities. Encouraged by Pablo Chill-E, he returned to music in 2018, gaining significant attention in 2019 with his track "X Dinero." This success led to collaborations with artists like Harry Nach, Polimá Westcoast, and AK4:20. Notable releases include "Cochinae" with King Savagge, "Tranquila," "Ganas," and "Perrea KTM." In 2020, Julianno Sosa faced legal issues in the U.S., resulting in a five-month incarceration in New Jersey, reportedly for illegal firearm possession. After releasing the album Finalmente Rico in 2022, he was detained again in June 2023 and subsequently deported to Chile, where he encountered further legal challenges, including an arrest in August 2023 for evading a police checkpoint and injuring an officer. Finalmente Libre, his next album, arrived in 2024. In March 2025, while en route to a video shoot in Peñaflor, Santiago, Julianno Sosa survived a shooting incident, sustaining two gunshot wounds. Later that year, he dropped the album Finalmente Feliz, featuring contributions from Jere Klein, Gino Mella, King Savagge, Bryartz, Jairo Vera, and Marcianeke.
