Valentim Frateschi, a 21-year-old São Paulo–born composer, producer, and arranger, has emerged as a dynamic force in contemporary Brazilian music. As the bassist and songwriter for the band Os Fonsecas, he has honed a distinctive sound that seamlessly blends Música Popular Brasileira (MPB), jazz, and indie influences. His debut album, "ESTREITO," released in September 2025 under Seloki Records, showcases nine tracks composed between 2019 and 2022, reflecting a journey through experimental textures and Brazilian popular song. Frateschi draws inspiration from artists like João Donato, Jards Macalé, and Arthur Verocai, as well as contemporary acts such as Crumb and BADBADNOTGOOD.
