Gene Tyranny

Robert Nathan Sheff (January 1, 1945 – December 12, 2020), known professionally as "Blue" Gene Tyranny, was an American avant-garde composer and pianist. "His memorable pseudonym, coined during his brief stint with Iggy and the Stooges, was derived partly from Jean, his adoptive mother’s middle name," wrote Steve Smith, in his New York Times obituary for Tyranny.
