After a quick listen - it seemed to remind me of Bartok in some places, but then other snippets remind me of Ravel. Sorry, this is an odd one for me. Anything Classical and Romantic, I'm far better at - but this is not my area of expertise.
Hi Visitor You have probably already thought of it... but maybe post a comment on YouTube asking for the composer? It really is a great piece and strange the op number is mentioned but not the composer I wondered if all contestants were required to play something by the same composer in this round, but couldn't seem to find this information, either.
