The Places - Potsdam owes it's development as a garrison town to the soldier king of Prussia, Frederick William I. The park and palaces of Sanssouci, however, largely reflect the very different taste of his son, Frederick the Great, who reigned from 1740 to 1786. The park of Sanssouci, established first in 1725, includes later changes in a number of distinct horticultural styles, with lay-out in Dutch, French and English taste. The Music - Bach's set of six concertos known as the Brandenburg Concertos was completed in 1721 at C+¦then, where Bach was director of court music, possibly using some compositions written during earlier years at the court of Weimar. Bach presented the set to the Margrave of Brandenburg, prefaced by a dedication in French, from which it seems that the prince had asked Bach for something of his at a meeting some two years earlier in Berlin. There is no indication that the works were performed, and at the Margrave's death in 1734 the manuscripts were sold, apparently in a lot of 77 concertos 'by different masters'. The fame and wide popularity of the Brandenburg Concertos was to come later. Included here are the first three concertos and a Siciliano.
