I'm disappointed that the recording isn't there now. I liked it alot, despite my minute crit. So, Poulenc actually has them at rather equal volume at those places. Well, sometimes it's a matter - as gerry says, too - of placement. I wonder - since we are listening to a recording instead of live - that the instruments might sound perfectly fine with enough distance between.
Recording is probably just as difficult to do right as performing. It's amazing how little recording things make instruments come 'too close' to one another and sort of cancel each other out. I know virtually nothing about recording, but I know what I like to hear. So, i use my normal language to imitate the sounds much like people do with car mechanics.
