The Holy Trinity of popular Brazilian music

In Ciro Santilli's view, the following three artists form a Holy Trinity of popular Brazilian music:

Elis Regina is not far though.

Ciro remembers quite clearly when he was riding the car with his parents when he pre teen, and he could not understand why they seemed so obsessed with The Trinity et al. Ciro in particular remembers listening to Video 61. "Refazenda by Gilberto Gil (1975)". They had picked it up of course from the 70's and 80's when they were younger.

Young Ciro would also always confuse who was whom from the three of them.

Then Ciro got older, and he understood, they are mind blowing. You do have to look back in time a bit though, lots of lukewarm stuff on later periods. The military dictatorship in Brazil was good for music.
