If you enjoy any kind of music you will love the MIM. They have done a terrific job providing the history and examples of almost any musical instrument you can imagine. And, as a bonus, you get to hear them being played in their original environment. They have a "hands on" section for the kids but this is really more of an adult museum. Most children wouldn't appreciate seeing John Lennon's piano that "Imagine" was composed or George Benson's guitar unless they can relate. For us old folks... this place is a little slice of music paradise that takes us back through time as well as an educational experience.
The theater is also a terrific venue to see live performances. All the seats are great but some are surprisingly fantastic. I'm not telling which ones those are because I want them to be available next time I go. You will have to find them for yourself:)
