Composer, pianist, arranjer and producer. Founder and member of A Cor Do Som, Mu has had his compositional talent confirmed by the hits "Sapato Velho," "Coisas do Coracao" with Paulinho Tapajos), "Terra do Nunca" (with Aldir Blanc), and by the music written for the soundtracks of the films A Dama do Lotacao, Os Sete Gatinhos, Navalha na Carne (all by Neville de Almeida), O Novico Rebelde, Xuxa Requebra, and Xuxa Popstar (all by Tizuka Yamazaki). His first solo album was the LP Meu Continente Encontrado (1985), that had the special participation of Luiz Eca, Egberto Gismonti, and Ze Luiz. As a sideman on live performances and recordings, Mu has worked with artists like Chico Buarque, Jorge Ben Jor, MPB-4, Alceu Valenca, Moraes Moreira, Fernanda Abreu, Legiao Urbana, Luis Caldas, Paulinho Moska, Gabriel O Pensador, and Marina Lima. Also a producer, Mu received a 15-diamond CD for his work for the collection Biblia Sagrada, which sold over 15 million copies. Mu debuted in the artistic career at 16 in the group Semente. In 1974, he became a member of Jorge Ben's Banda do Ze Pretinho. In the next year, the group that would be known as A Cor Do Som (Mu, his brother Dadi, Gustavo, and Armandinho) was Moraes Moreira's support band and recorded his first album. In 1976, Mu wrote "Sapato Velho" (with Claudio Nucci/Paulinho Tapajos). The song became a hit and was re-recorded several times, which confirmed Mu as a composer. His "Espirito Infantil" was classified with fifth place in the first National Choro Festival, organized by TV Bandeirantes. In 1978, Mu backed up Gilberto Gil at the Montreux Festival (Switzerland) and in his tour through France, Argentina, and Brazil.
