Inzul is a Peruvian indie pop band formed in 2014 by Stefano Toller and Gianfranco Arias, who began crafting their sound in a basement in the district of Miraflores, Lima. Driven by a passion for songwriting and experimentation, they honed their craft until gaining recognition in the local scene. By 2015, they reached the finals of Festival Claro, connecting with Sony Music representatives, and soon after were selected to represent Peru at Primavera Sound 2017 in Barcelona, one of the world's leading alternative music festivals. The same year, they performed at the renowned Selvámonos Festival in Oxapampa, and followed up with appearances at Vivo x el Rock in 2018 and 2019, as well as Día de Rock Peruano in 2019. Subterráneo, their debut album, came out in 2018. After a brief hiatus from new releases, Inzul returned in 2021 with the single "El Muro," exploring more pop-oriented textures, followed by "Esta Noche," a softer, melodic track centered on themes of love and romantic anticipation. In 2022, the duo dropped the live album Inzul Acústico (En Vivo), followed by the studio full-length Las Cosas Que Nunca Te Dije the following year.
