‘Celebrating 30 Years of Baroque’ is Paul Dyer’s theme of the 2019 Season of the Australian Brandenburg Orchestra; 30 years of distinguished achievement is certainly worth celebrating. The season is marked by what I would call a return to core business. Bach, Handel and Vivaldi are given appropriate prominence. The anniversary season opens in February with the Orchestra’s namesake works: Bach’s Brandenburg Concertos; five of the six concertos which Bach dedicated to the Margrave of Brandenburg in 1721.
