I just found some rather strange comments in another thread about Edu Lobo starting the Tropicalismo (Tropicalia) movement. That's simply not the case--Edu was always pretty firmly in the Bossa camp, especially circa 1967 when Tropicalismo started. It is Gilberto Gil and Caetano Veloso who are always credited as being the founders of this movement, specifically during the 1967 international song festival, which was televised and was a huge national event in Brazil. The movement also had significant contributions from Chico Buarque, Os Mutantes and Gal Costa. It was Gil and Caetano who released the album most associated with the movement, "Tropicalia," in 1968. Edu was certainly an experimenter and incorporated a lot of influences in his work, as did the Tropicalists, and while he did hint at some social protest issues in his songs (notably, Upa, Neguinho!), he wasn't known for the virulent protest stances of Gil, Veloso and Buarque.
