Sergio Valdeos is a Peruvian guitarist, arranger, and composer. After a busy and successful career in Peru and Brazil, Sergio moved to Geneva in 2016 in search of new musical horizons.

He studied in Peru with guitarist Carlos Hayre. He then continued his studies in guitar and arranging in Brazil.

As the guitarist for Susana Baca (winner of the 2002 Latin Grammy) from 2001 to 2009, he recorded the following albums with her: "Espiritu Vivo" (2002), "Travesias" (2006), "Seis Poemas" (2009), and "MAMA" (2010). In Peru, his recordings as an arranger and guitarist are highly regarded: "Jazz con sabor peruano" (TDV, 2006), "Pilar de la Hoz", "Kenyara" (2001), and "Nouba" (2010). With the group Kenyara, he released "Despertar" and "Sayariy" (2012) with Rosa Guzman and Edward Perez.

Together with Carlos Hayre, he led a research project on guitar rhythms from Peru’s Pacific coast between 2008 and 2011, supported by the Catholic University of Peru. He has led master classes on Peruvian and Latin American rhythms at the most prestigious music schools in the Americas and organized “Rodas”—jam sessions—to exchange repertoires with musicians of different styles, always in search of new musical languages. In Brazil, he is a founding member of the Maogani guitar quartet, which has won several awards for its musical output, including the 2005 Prêmio Tim, the 2004 Prêmio Rival BR, and the 2002 Caras Prêmio, among others. In 2012, he recorded the album "Pairando" (2014—winner of the “Prix de la Musique – Best Instrumental Group” award).
In 2016, he was once again nominated for the Prix de la Musique for the 2015 album "Canela", recorded in Lima, where the group Maogani and singer Renato Braz explore the American repertoire. In 2010, he formed the group Los Cuatro in Rio de Janeiro, which focuses on the instrumental repertoire of Brazilian choro. In 2013, he released the album "Os outros caminhos do choro", which features his compositions inspired by Latin American rhythms.
