Hi bill
If you haven’t already, try and get to some of the keyboard festivals in the UK, as you will really enjoy the performances from Artists from all over the world.
Also have a look at Mark Whale here. (Main performance starts about 2.5 minutes in)
It also features the Bose L1 speaker system that everybody talks about.
