Nikolaus Harnoncourt is credited with making historical performance practice respectable in Salzburg as well. The memorable debut concert of 1980 was the prelude to a long success story that culminated in the Mozart Week 2006, when Nikolaus Harnoncourt was Artist in Residence and gave his acclaimed ceremonial address on 27 January on the occasion of the 250th birthday of Wolfgang Amadé Mozart. The inaugural concert and rehearsals from 2006 can be heard on this album. This 3-CD edition covers the era of Nikolaus Harnoncourt and his influence on the interpretation of the music of Wolfgang Amadeus Mozart. Between 1980 and 2006, the conductor succeeded in sensitising both musicians and audiences to new playing and listening habits and evolved from a pioneer of historical performance practice to an acclaimed maestro. When Nikolaus Harnoncourt made his debut at the Mozart Week Salzburg on 27 January 1980, concert audiences were at the feet of conductors like Karl Böhm. In those days, bea utiful sound and melody were the central themes of an interpretation. Following instructions in the original scores, Harnoncourt had articulation, tempi, melodies and accompanying parts played with a new style and emphasis. The reactions to the concert in Salzburg at that time were varied. In addition to strong slurs, there were also effusive hymns of praise. 20 years later, Nikolaus Harnoncourt became Artist in Residence at the Mozart Week 2006 and was the keynote speaker on the occasion of the 250th birthday of Wolfgang Amadeus Mozart. In the meantime, his ideas of historical performance practice had spread worldwide and developed into the basis of a new generation of concerts and musicians. In this CD edition, his inaugural concert of 1980 is juxtaposed with rehearsal recordings from 2006. Bo th recordings provide fascinating insights into the intentions of the famous conductor
