Camerata Salzburg Concert Hall, HK City Hall Reviewed: October 22 Chamber orchestra Camerata Salzburg gave a lively, refined and cliche-free performance of an all-Mozart programme on Sunday evening at City Hall, as part of a concert series celebrating the composer's 250th birthday. The K136 Divertimento, an early work for strings that opened the concert, highlighted the chamber orchestra's style - one that combined the leanness of period performance with the human touch of traditional Mozart playing. The string sound was velvety and shimmering, displaying fine legato, brisk articulation and clearly delineated phrases. The musicians' vigorous playing never became boorish, nor did their dynamic contrast ever disrupt the elegance of the piece. Violin Concerto No5 followed, with Julian Rachlin as soloist. The performance had the lively intimacy of a high-calibre chamber recital. Rachlin's tone occasionally seemed too small to project above the orchestra - perhaps he should have played more imposingly. But his virtuosity in the cadenzas, his fastidious attention to tone colours and shades of emotion in the Adagio, and his endearing, conversational manner in the Rondo all attested to the artistry of this renowned violinist. The second half of the concert began with the popular Eine Kleine Nachtmusik, which received a refreshing treatment without romantic indulgence - although both the Romance and Menuetto might have benefited from a less hurried approach. The highlight was the final work: Symphony No40. The winds were a little too loud at first, but the group soon adjusted to a comfortable balance. Whether it was the cushioned string notes at the start, the pathos of the first movement, or the convincingly delivered dialogues between winds and strings in the Andante, the conductor-less ensemble played with more unity, verve and charm than many manage with conductors. The final movement summed it all up, ending the night with engaging musical drama.
