Los Holy's, formed in 1966 in Lima's Pueblo Libre district, were pioneers of instrumental psychedelic rock in Peru. Initially known as Los Sharks, the band comprised Marcos Goyzueta (lead guitar), Arturo Matto (rhythm guitar), Oscar Sáenz (bass), Renzo Carozzi (Farfisa organ), and Walo Carrillo (drums). Their 1967 album, "Sueño Sicodélico," showcased an innovative blend of psychedelic and surf rock, featuring standout tracks like "Piedra de los 12 Ángulos" and "El Hombre Desnudo." Despite their brief existence, disbanding in 1969, Los Holy's left a lasting impact on Latin American rock, inspiring future generations with their experimental sound.
