Paul Dyer says he sees playing Johann Sebastian Bach as the "ultimate experience for a musician," rightfully so, the same goes for a listener too, and in naming his orchestra after the most famous of Bach's instrumental works, he puts his money where his mouth is, but more importantly so in the fine, detailed playing, expressiveness and unforced enthusiasm, which show much care and thought in the preparation of this program. Sydney perhaps is not and never claimed to be a great Bach town, but either way, as a lover of his music, I can feel sorely deprived of him, despite the odd performance on period instruments or otherwise over the last two years. So it felt like a parched walker coming upon a water-hole to hear a program where the whole first half was devoted to Bach and the rest to contemporary (with a small 'c') music. The ABO has pulled out many of the stops (within reason), assembling a larger-than-usual group of 10 violins, four violas, three cellos, one bass, two flutes, three oboes, one bassoon, two horns, three trumpets, theorbo, timpani, organ and harpsichord, as well as a choir of about 35, though of course not all of these for all pieces.
