Johann Sebastian Bach did not write any cello concertos. Or did he? Many of his music manuscripts disappeared after his death. Included in that lost treasure may have been a couple of cello concertos. Bach wrote six suites for cello and three sonatas for viola da gamba, so, yes, why not a cello or a gamba concerto?
Here is the Concerto In F Minor BWV1056 arranged for cello and piano.
