Siete-7 Black is the stage name of Spanish musician, producer and composer Israel Delgado (born 1971 in Paris, France). He moved to Burgos, Spain, at the age of six, where he was raised in the Gamonal district. Largely self-taught, he developed his musical skills from an early age. Emerging in the early 1990s, Siete-7 Black is considered among the earliest Spanish artists to incorporate elements of funk, hip-hop and contemporary R&B production into a cohesive sound. His work reflects influences from artists such as Parliament, Cameo, Grandmaster Flash and Bobby Brown, combining funk, early hip-hop and New Jack Swing aesthetics. He gained national recognition in the mid-1990s with the single "Somos el futuro", which received significant airplay and led to appearances and tours associated with Los 40 Principales. Although he did not continue releasing music under this alias, Delgado went on to develop a successful career as a composer and producer for Spanish television. His work includes music for programs such as "Crónicas Marcianas", "Operación Triunfo" and "El Hormiguero", among others. Despite a relatively limited discography under the Siete-7 Black name, his recordings are considered an early example of New Jack Swing-influenced production in Spain during the 1990s, when this approach was still relatively uncommon.
