Shortly after this, Lutosławski started work on his Second Symphony, which had two premieres: Pierre Boulez conducted the second movement, "Direct", in 1966, and when the first movement, "Hésitant", was finished in 1967, the composer conducted a complete performance in Katowice. The "Second Symphony" is very different from a conventional classical symphony in structure, but Lutosławski used all of his technical innovations up to that point to build a large-scale, dramatic work worthy of the name. In 1968, the work earned Lutosławski first prize from the International Music Council's International Rostrum of Composers, his third such award, which confirmed his growing international reputation. In 1967 Lutosławski was awarded the Léonie Sonning Music Prize, Denmark's highest musical honour.
