If you have any appreciation for music, this museum is a "must-see." As a self-proclaimed former band geek, I was in heaven. I arrived at 11:00am and didn't leave until the museum closed at 5:00pm. There are instruments and exhibits representing nearly every part of the planet. The museum does an incredible job at showcasing just how diverse the world's cultures are while still proving that we are all linked through the wonders of music.
My only nit-pick is the wireless headphone system that is used throughout the galleries. Maybe my wireless receiver was low on batteries, but I had to awkwardly wave it through the air to pick up the signal for the exhibit I was standing directly in front of.
Don't forget to check out the Artist's Gallery on the bottom floor which currently features some Elvis memorabilia.
