The baritone Thomas Hampson is a popular figure at the Salzburg Festival, having appeared there regularly since 1988, and at his Lieder recital with pianist Wolfram Rieger at the Haus der Mozart, one sensed a warm rapport between him and the audience. His programme consisted of Schumann’s Liederkreis, Op. 39, Dvořák’s Zigeunermelodien and Mahler’s songs based on the text of Des Knaben Wunderhorn.
