At some point the DJ at the bar where I was working played some song in Portuguese - a male voice singing in a very unusual and interesting way. Indeed he played several songs in Portuguese, but at the end of the night I asked him if he remembered which could have been the one that stood out. He said "something Santara," as far as I remember - I think I remember the surname, because it sounded like "Santana," but I don't remember the first name and I didn't have the time to write it down. Has anyone got a clue? I tried googling "Santara Brazilian Singer" etc., but didn't get any results.
