What do you think of this artistic "liberty" of sorts?

A friend of mine played the Mozart D minor Fantasia today for our school's talent, and at the part of the piece (appears first at bar 17) where the D minor chord goes into a diminished chord, instead of playing softer, he played louder (still keeping the note value in mind). When I asked him politely about what drove him to do that, he said he was highlighting the more dissonant chords, as he also did in the D major section. I thought of this, and it makes sense, especially since he did it continuously throughout the piece.
What are your thoughts?

Well as always it depends haha.

"why did you play louder Barenboim" and you get an opinion of somebody more qualified than myself...

I've seen the Barenboim masterclass, it was quite humourous. I brought this up to my teacher (whom I just saw) and he actually says it appeals to him personally more than getting softer.
Interesting discussion.
Also, I cannot pause my youtube right now... The F minor Chopin concerto is too good to resist...

With a name like 'chopin' I think lumberjack, not pianist ;P

The video is hilarious, and what's even funnier is that most editions have a piano where he insists it's forte. Makes the poor guy playing for Barenboim appear feeble minded, but it's not his fault. And Barenboim evidently knows his stuff, but what would have been more impressive is if Barenboim didn't indicate any doubt. Or at least told us why the discrepancy exists.

Back to the question;  If it sounds good and tasteful..go for it
