The Verdi Messa da Requiem is probably the best known Requiem in the repertoire. Many great conductors have recorded it. I’m thinking of Toscanini at New York/1951, Victor De Sabata at Milan/1954 and probably the best known of all Carlo-Maria Giulini at London/1964-65. Some more recent versions have proved popular notably John Eliot Gardiner using period instruments in London/1992, Claudio Abbado at Berlin/2001 and also Nikolaus Harnoncourt at Vienna/2004.
