One of the pioneers of blues in Brazil, Celso Blues Boy has played some dates with B.B. King, both in Europe and Brazil, with his participation in the track "Mississippi: Sobre Robert Johnson" (Celso Blues Boy) included in the CD Indiana Blues (1995). His biggest hits are "Amor Vazio," "Aumenta Que Isso Aí é Rock'n'Roll," and "Fumando na Escuridão." In his 27-year career, he has recorded nine albums, having released the first one (Som Na Guitarra) in 1984. At the age of four he performed on a radio show managed by his grandmother. After working as sideman for artists like Raul Seixas and Sá e Gurabyra in the '70s, he formed the band Legião Estrangeira in 1976. In 1980, the advent of Fluminense FM radio specializing in Brazilian rock offered him some airplay and recognition. ~ Alvaro Neder, All Music Guide
