I downloaded Avguste Antonov's rendition, and noticed that this is not actually that sonata. The three tempi are the proper ones to go with XVI:16, with which I'm familiar, but the tempi performed obviously belong to another sonata. Also, the key is listed as D, while XVI:16 is in E Flat. All that said, I was very impressed with the work played under that name, as well as Antonov's performance; can you tell me: (1) What is the work played as XVI:16, and (2) Is the actual XVI:16 located in the list of sonatas under another title? Thank you very much for your help.
