Can observe some useful playing techniques in this video. Some interesting observations used by both Jonathan and Tom. For instance they used hand over hand quite often. Something you don't see very often was double thumbing by Jon.
And Tom's use of the middle (soft) pedal to make very subtle intonation changes on the Yamaha S6 along with the sustain pedal. Using both feet and quite some coordination. That middle, soft pedal physically moves the piano's keyboard as you can see from the treble end camera shot..
That Hill organ provided well thought out (orchestral stop) registrations which Jonathon used very appropriately.
(Love that clarinet stop). Interesting comment in the chat where the comment was made had that selection been played during the offertory, he'd have been "forced" to put a larger amount on the plate.
They, being brothers, seem to bring a special chemistry to their performances. All in all, an outstanding musical event to witness.
