This is my two cents. Gump says " For this tour, we're not going to be using the full V-drum kit on the back. We're not going to be spinning. It's going to be full tilt Rush songs and there will probably be a whole lotta old stuff in it."
So a special one of a kind kit, and perhaps the last time we see Neil tour. I think it's plausible.
1. In terms of sound, the acoustic instruments just sound better. So on that front it's a win.
2. Visually it would look cool.
3. A full rendering of Xanadu, La Villa and Jacobs Ladder would be awesome.
In the past he had said that he liked the control and consistency of the samples. Putting mics to all that gear and getting consistently good sound was always a challenge. These days I think the task would be much simpler. For one, they use an automated mixing console. No one has to boost individual levels of each input when Neil goes to play the percussion. The entire routines can be pre-programmed. Secondly, as another poster pointed out, the actual stage is a much quieter place since removing all the cabinets. But even if they had not, the problem was not insurmountable. To me, the biggest issue in terms of stage noise would have been the floor monitors, and they are but a distant memory. This is totally doable. Wishful thinking? Perhaps, but I don't think its out of the realm of possibility.
