The group Saecula Saeculorum was the first prog rock band of Marcus Viana and also the foundation of what would become Sagrado Coração da Terra. As very close friends, the band rehearsed tirelessly in the mid-'70s and bandmembers preserved several demo tapes from this period. Impressed by one of these demo tapes, Warner asked them to sign a contract in 1976. After a lot of discussion (mainly because of Warner's demands that some songs be cut to fulfill special requirements, which the band disagreed with), the band refused the deal and continued their rehearsing. After too much effort and almost no recognition, they disbanded and each musician went their own way. A reunion was promoted in 1996 in order to release the CD Saecula Saeculorum, but no gigs were performed. Some Brazilian critics said that the band was the true progressive version of Clube da Esquina, a famous and impressive musical movement born in Minas Gerais (a state in the southeast of Brazil) that included, among others: Milton Nascimento (from Som Imaginário), Flávio Venturini (from O Terço, 14 Bis), and Beto Guedes. ~ Cesar Lanzarini, Rovi
