Kevin Sutton: Ignaz Pleyel MusicWeb. (englanniksi): "At one time regarded as one of the greatest living composers, Pleyel’s influence stretched all over Europe and even to the United States..Although he outlived the younger Beethoven by four years, the shadow of the giant from Bonn was too long for Pleyel to surpass, and his music fell completely out of fashion."
