Cool! I heard it at Benaroya for the first time this two days ago, and it was great! A beautiful lush peice that made musical sense - that is, I felt myself aligning with the music. I'd never heard the Saint Saens before, so I heard it with new ears (though my dad had told me it is good, and he's usually right!). I found the introduction of the organ into the peice (about 8 minutes in) a bit abrupt, but once it was there, it was welcome. Never overbearing, never too "churchey"! The audience communicated lots of appreciation.
And yes, that organ is something. So clean sounding, no hissing air or pumps to be heard. Base that you can feel, almost count the hertz at the lowest notes. Not overbearing but complimentary.
They also played Strauss - later used as the theme for "2001 Space Oddyssey" and wow that organ could shake the house.
Let us know what you think Mceljo.
