The World's First Global Musical Instrument Museum.
We were there for 2 hours, and only got through parts of Africa, the Middle East, Asia and Latin America. My back started hurting from being on my feet for so long because it's HUGE.
They have audio headsets that sync up to the displays as you get near them. All you have to do is adjust the volume if you need to. I now know that I enjoy the music of Madagascar.
I met some people at work who said the spent the whole day there. Started at one area, went down and had lunch in the cafe midday, then headed back up for the rest of the world.
Gotta look into a membership because it's awesome and they're not even done with it yet!!
