Inviting guest musicians Osmo Vänskä and Alisa Weilerstein to the Sydney Symphony makes an artistic match the muses approved of, not to mention the heavens. They only came for three performances in Sydney, and how they found time to rehearse this dense program thoroughly is a mystery to me, though a shared musical spirit and understanding seemed to be on their side in this performance. It was a rare conjunction of various uncontrollable elements. The program too is very interesting. The Sydney Symphony has found a ‘new’ Tchaikovsky piece, apparently never having played Voyevoda before, and has not played the Prokofiev sinfonia concertante for 40 years. Beethoven is always interesting (at the very least), but here we have a unique interpreter of his symphonies in Vänskä, who seemed even to find in Beethoven hitherto unheard connections to Prokofiev.
