Number four in the series, and as we move through time we move into the realm of HD and 4K too. See the changes made in 2009 to the attraction – the biggest in its history to date – then take a look outside, around the lobby, and then the whole Obama version of the show, shot with a combination of HD, 4K, and tripod. Audio is a brand new ALD / clean live mix that I hope is the best available to date.
