Of history is unwritten. I’m not referring to the obviously unaccounted prehistory etc., I’m referring to everything that happens that doesn’t make it into the history books. Your grandmother, you, whether or not people followed the career of a particular musician from another country or not.
Written history, that is, the occurrences that are being recorded “officially” are really quite few and far between. I suppose blogs are changing that, but only by the tiniest fraction.
