Dewey Owens published a masterpiece of a transcription with the Bach Chaconne. There are two editions, Lyra and a Lyon & Healy edition, I believe. I prefer the first, with slight modifications that are obvious to anyone who learns it. Lucile Lawrence embraced it and taught it to many of her students. I would not even consider any other edition. Dewey was an expert in writing for the harp, and as an organist, certainly had a good understanding of Bach. For someone who wants an impressive Bach solo to play in a recital, this is it.
