Help with competition repertoire

[ned174849]

I’m currently choosing and starting repertoire for a competition in the following months as well as competitions in general. For this particular competition, without too much detail basically requires 50 minutes of repertoire and a Bach prelude and fugue. For the Bach I already chose the C# major from book one. As far as other pieces go I’m currently considering doing Medtner’s sonata tragica op 39 no 5, a larger work or collection of works, and a more 20th century work (currently considering either a selection from Messiaen Vingt Regards or Liebermann Gragoyles Op 29.) Something like that or maybe even Ravel’s Valses Nobles et Sentimentales. As for the larger scale work I am currently not sure what I want to do and I’m open to suggestions. Taken all the other repertoire I listed as possibilities it would need to be something at least around 20 minutes in length. Any suggestions and thoughts on the repertoire I mentioned are welcome
