Duo Mares is Kelly (@kcheretti) and Luiz Spiga (@spiga).
Some Kelly words:
I'm very excited to present this song to you for two reasons. The first refers to an affective relationship that I have with the tune. I first heard when I was a teenager. Daring and avant-garde, that are well expressed by this song.
(If you want to hear the original version, to let the youtube link here: 
)
And the second reason refers to representativeness of this band into the “Tropicalismo”, musical context during the military dictatorship in Brazil.
The "Mutantes" was formed by Arnaldo Baptista, Rita Lee and Sergio Dias and is considered one of the main Brazilian rock groups. Recorded music "Ando meio desligado" was released in 1970 on the album "Divina Comédia ou Ando meio Desligado".
This version was a result of the work that I have with my partner and guitarist Luiz Spiga, the Duo Mares!
P.s.: sorry for the cell phone!
Thank You! @luzcypher and @pfunk.
