JOSEF Suk, artist in residence at this year's Arts Festival, is the great-grandson of Antoin Dvorak and grandson of the composer Josef Suk, and also the leading representative of the great Czech violin school. He is a world-class soloist, as well as a fine chamber musician. In 1964, Suk received a Czech state prize, in 1970 he was made an Artist of Merit, and in 1977 was named a National Artist of Czechoslovakia. His many awards include prizes for his recordings of violin concertos by Berg, Mozart and Martinu. Altogether he has made more than 200 recordings. Critics have noted that Suk has never tried to dazzle audiences with his technical virtuosity, but is more interested in the refinement of interpretation and the attainment of stylistic purity. His programme for his Hong Kong shows includes four Dvorak pieces and a sonata by Janacek, which is described in the programme notes as having an opening movement that ''is passionate and uncompromising, while the Ballada is gentle and graceful''. The programme adds: ''The third movement serves as a scherzo and the work ends, rather unexpectedly, with an Adagio, with the initial drama of this last movement gradually giving way to a mood of resignation.'' Brahms' Scherzo in C minor is next, and a Sonata in A by Franck closes the programme. Suk plays two Stradivarius - The Tate from 1710, and The Libon from 1729. Apart from giving a solo recital, he will also be the soloist in the Suk Chamber Orchestra's two festival concerts, and appear with pianist Josef Hala and cellist Jian Wang in a special trio concert that promises to be one of the highlights of this year's festival.
