Himmelsburg is the name of the former chapel of Wilhelmsburg Castle in Weimar; Johann Sebastian Bach's "workplace" during his time as court organist and chamber musician at the Weimar court. This chapel was irretrievably destroyed in the great castle fire of 6 May 1774. In Bach's time; a high musical culture prevailed at the Weimar court. The young Prince Johann Ernst; himself a good violinist and harpsichordist; was enthusiastic about Italian music; and Bach was inundated with the latest concerti from Italy; especially by Vivaldi. In addition; there was close contact with the violin virtuoso Johann Georg Pisendel; so it is no exaggeration to call Weimar the concertante and violinistic cradle of Bach. On her new CD; Lina Tur Bonet interprets "all" of Bach's four concertos for solo violin. All of them probably date from his Weimar period. The two original concertos BWV 1041 and 1042 contain many stylistic references to Vivaldi. In addition; Lina Tur Bonet presents the reconstructions of the concertos BWV 1052r and 1056r; two harpsichord concertos that were almost certainly originally intended for violin.
