I've been so busy this week that I had completely forgotten about BMoF, which I usually write on Thursday evening. My husband just came around and asked me, "so, what are you posting this week?", and only then did I realize I should be writing the column... So we'll have a bit of an improvised BMoF today, but with a truly beautiful song, 'Pérola Negra' by Luiz Melodia, from his first solo album with the same name (1973). Next week I'll write a proper column on Luiz Melodia, but for now here's a bit of an appetizer.
