Carlo Gesualdo da Venosa (probably 8 March 1566 – 8 September 1613) was Prince of Venosa and Count of Conza.
As a composer he is known for writing intensely expressive madrigals and pieces of sacred music that use a chromatic language not heard again until the late 19th century.
However, the best-known fact of his life is his brutal killing of his first wife and her aristocratic lover upon finding them in flagrante delicto.
The fascination for his music and his crimes have gone hand in hand.
