Michael, thanks for posting these links, I have learned a lot in a few hours. Things I thought I knew, and a few things that I hadn’t considered. Just from the link I quoted.

Elbphilharmonie Hamburg
The task was to create one of the world’s best concert halls … It is unfortunately in German … but it is the journey
worth it … if you can get a ticket …

These guys are passing the house door. One of the tasks was that the ship’s horns etc. could not naturally be heard in the concert hall … Thanks Cunard Line for demo …

They often send live…so try signing up on their Facebook …

Hamburg’s concert hall is astounding.

i also relish the fact it cost $850,000,000. That is, a concert hall which rivals the cost of a new football stadium - money much better spent on art.

Missing some zeros?

Oops. Fixed.

Thanks!

Wow great!

I love to look at things I can’t afford (at least if they are far enough above the budget) :wink:

Maybe some inspiration for @brodric‘s next investment :wink:
