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
Strathclyde Concertos of the "Strathclyde Concertos", Davies increased the number of soloists. The Ninth (1994) is scored for six woodwind soloists, while the Tenth (1996) is a concerto for orchestra whose finale is a sort of recapitulation of ideas heard in the earlier concertos. The first two concertos were recorded by Unicorn-Kanchana, with the composer conducting. The remainder were recorded by Collins Classics. This concerto is based on two pre-existent works: Haydn's overture "L'isola disabitata" and a two-part setting of the opening line of Ecclesiastes, "Vanitas vanitatum et omnia vanitas" by the early seventeenth-century composer Jan Albert Ban.
