A+ in my book and if you love music of all genres, you will absolutely love this place. From it's unique pyramid structure, to the invaluable memorabilia that is housed inside, this tour is one you will not forget! The gift shop is fab as well. I don't have a single negative thing to say other than you need all of the time you can get to tour it in it's entirety. Great place. Courteous staff. Kudos!
