He would have been 72 today. He's still missed in the world of music.
While some of his music is/was utterly distasteful (Flo and Eddie years)...I think in a hundred years, he will be in the music history textbooks as one of the most famous composers of the 20th century.
I suspect he will be one of those artists that will be remembered with the same reverence that some of the finer orchestral composers are regarded... His technical excellence and the demands he laid upon those working with him are examples of this few could hold a candle to...
