In cooperation with the International Mozarteum Foundation belvedere is publishing highlights of the Mozart Week from first beginnings until today. Contemporary history and the history of interpretation become audible on carefully restored sound documents in excellent sound quality. Moreover, the edition will also comprise current recordings from the Mozart Week and concerts throughout the season, using the most up-to-date recording and production techniques. The Mozart Week has taken place annually in Salzburg since 1956. Renowned artists have made their mark on this festival since its beginnings and created a distinct impact as regards interpretation, artistic analysis and musical performance. Concerts of the Mozart Week have been recorded on radio and television since the inauguration of the festival. The treasures in the archives of these concert recordings are now being reissued. The album "Wilhelm Backhaus plays Mozart" contains a recording of the pianist's recital from 1956, the 200th anniversary of Mozart's birth and also the year when the Mozart Week was founded, and recordings from the recital in 1967. It offers an interesting opportunity to compare Backhaus's interpretations and the implicit relationships Mozart's compositions. Wolfgang Schaufler writes: "We have to bear in mind that Backhaus worked closely with Hans Richter who conducted the first performances of some works by Brahms."
