A début in 1958 was that of the Royal Concertgebouw Orchestra of Amsterdam, one of the most famous and versatile orchestras in the world.The Concertgebouw gave five concerts that summer, the first of which was devoted to Mozart. Even in a live performance, Wolfgang Sawallisch phrases the music with extreme precision, proving himself as great a Mozartian as he was a Wagnerian after his début in 1957 at the helm of Tristan und Isolde. No less acclaimed by this date in his career was the soloist, Friedrich Gulda, whose performance provided the concert with its point of calm repose, countering virtuoso expectations and in that way anticipating the musical 'chameleon' of the later period.
