There's a -quite- good performance by Jonathan Powell, from the same 2010 "Indian Summer in Levoca" festival that also had Powell in Bax's quintet and I think Delius' cello sonata too, of Medtner's piano sonata in E minor "Night Wind", in 2 videos (for splitting-up) on YouTube. I believe it might be one of the best performances of the sonata I've heard so far, something like the Ogdon (my earlier favorite) in better sound and without the (seeming??) cuts,- ... I mean, like the Ogdon, managing that balance of control and the strong feeling of danger/risk/abandon I think the work may need.
Which Bax quintet do you have in mind, Eric?
piano quintet in G minor (GP 167, 1915), sorry. I wasn't sure there was more than one quintet by Bax with a piano part, but come to think of it there may well be!...
