There's a lot of stuff, here, but it is disorganized. They really need to hire a good curator who can design a series of exhibits with a through line. The experience was very much: "Look! Guitars! Now some costumes! Here are some exhibits that are kind of chronological, but wait! Presley! Ok, now the Sixties, but no Beatles, no Hendrix, no Dylan, no Stones...no, wait! Here are big exhibits for the Beatles! The Stones! Hendrix! Ooops, still no Dylan. Oh, look disco happened, and so did Punk. Oh, grunge is over here! Wait, more guitars. A drum kit! More guitars!" It was bewildering, incoherent, and the opposite of illuminating. In a lot of ways, I feel like I know _less_ about rock and roll, now.
This exhibit space is in fundamental tension with Rock and Roll's history of being a protest medium, and this is never reckoned with in any fashion. This creates a very weird and difficult cognitive dissonance. This is increased by the complete lack of focus.
Finally, the soundscape was often unpleasant. The various exhibits had their own sound tracks, as you would expect, but they overlapped and conflicted. There was a frustration of having only snippets of songs I wanted to hear more of, too. Also, frankly much of it was simply not loud enough! The Who, for instance, really does need to be played at volume to be appreciated. I get that this is a hard problem, but at the same time, the solutions employed are not solutions, they are examples of the problem.
If there's a particular piece of memorabilia that they have that you want to see, you should go. Otherwise, really not worth the money, in my opinion. Kind of like a Hard Rock Cafe without the food.
