Brandenburg Concerto No. 5 the concerto, with a preface by Besseler, in 1964. In 1975 Dürr's edition of the early version was appended to the NBA Series VII Vol. 2 publication of the "Brandenburg Concertos". The violone part for the third movement of the NBA edition of BWV 1050a was based on a spurious cello part for the BWV 1050 version of the concerto: Dirksen deemed the result of that combination unconvincing. Recordings of the fifth "Brandenburg Concerto" were released on 78 rpm discs: In 1973 Wendy Carlos included a Moog synthesizer performance of the fifth "Brandenburg Concerto" in her second "Switched-On Bach" album.
Organ concertos, Op. 4 (Handel) of his oratorios Esther and Athalia. During this period Handel prepared the 16 movements of the four organ concertos HWV 290-293, of which 10 are reworkings of previous compositions with the remaining 6 largely newly composed. HWV 292, completed in March 1735, contains the most new material, although even there the ritornello of the first movement is a borrowing from Act 1 of Alcina. It featured in the April performances of Athalia at Covent Garden. The other concertos were first heard in March, HWV 290 and 291 in Esther and HWV 293 in Deborah. Handel completed Alexander's Feast in January
