A year after his Cliburn Competition victory, in 1967, Lupu won the first prize in the George Enescu International Piano Competition. Two years later, in October 1969, he won the Leeds International Piano Competition; he performed Beethoven's Piano Concerto No. 3 (Op. 37) in the Finals. The following month, in November 1969, Lupu played his first solo concert in London; Joan Chissell of "The Times" wrote about his performance of Beethoven's Piano Sonata No. 7 at the recital: "He brought what seemed like a lifetime's experience to its alternating desolation and pride. Never could music come nearer to speech."
