Brandenburg Concerto No. 5 "Brandenburg Concertos" takes a central place. Nonetheless around half a dozen of Bach's extant concertos, including some of the "Brandenburg Concertos" and lost models of his later harpsichord concertos, seem to have had their roots in his Weimar period. Most of what Bach may have left with his employer in Weimar perished in a fire destroying Schloss Weimar in the 1770s. In 1719 a new large two-manual harpsichord arrived in the residence of Bach's then-time employer at Köthen. BWV 1050a, an extant early version of the fifth "Brandenburg Concerto", may have been conceived for this instrument, but that seems unlikely
RBB Brandenburg RBB Brandenburg RBB Brandenburg (until May 2003 ORB-Fernsehen) was the "third television channel" for Brandenburg, Germany from January 1992 to March 2004. Until May 2003, it was organized by Ostdeutscher Rundfunk Brandenburg (ORB), then by its successor, Rundfunk Berlin-Brandenburg (RBB). On 1 March 2004, the two regional television channels of RBB - "RBB Brandenburg" and "RBB Berlin" - were integrated into the new rbb Fernsehen. The programme was launched on 1 January 1992 under the name "Fernsehen Brandenburg". In the initial build-up phase, the then ARD cultural television programme Eins Plus was taken over from 3 p.m. to 5.15 p.m.
