His participation in the group Saecula Saeculorum opened the doors to the progressive rock world. When the band dissolved, he created two distinct groups who rehearsed more than they performed: Ícaro and Conclave dos Druidas (the Druid's Conclave). In 1979, he started a new project called Sagrado Coração da Terra, mixing vocal and instrumental music in the progressive/symphonic rock line with emphasis on ecological and spiritual matters.
In addition to producing his own CDs, Viana composed soundtracks for TV series, films, theater, children's musicals, and ballet. He has received several prizes as an author of jingles for radio and TV commercials. ~ Cesar Lanzarini, Rovi
