You'll probably feel that they don't have enough stuff on your favorite person, but they do have a whole lotta goodies. You could spend a week at the information kiosks they have on one of the levels (I forget which one; deal with it). You can look up all kinds of stuff on just about any R&R'r, and usually hear an interview or two. Each one has two headsets and a touch-screen. The interface is real straightforward, so you don't have to be a compu-geek to use it.
I really enjoyed looking at the John Lennon memorabilia. They have a report card from his grammar school days, one of his daily underground newsletters from the same era, and his Hamburg-era leather jacket, among other things. They have several of Jimi Hendrix's handwritten lyrics, and one of his favorite guitars, but I wanted MORE (I had to deal with it). Lots and lots of rocker's clothing on mannequins; a fair amount of instruments; tons of photographs (way too many of Andy Warhol for some reason); a bizarre Pink Floyd area (bizarre in a good, Pink Floyd-ish way); a one-hit-wonder booth; random exhibits on random rockers; a history of R&R on Radio area; and a whole lot more. One thing they DON'T have is very much at all on Stevie Ray Vaughan; which just doesn't get it (I've tried to deal with it but I can't).
At least one of the films has some cursing, references to drug use, and a brief scene of a topless hippie chick at Woodstock, so if you're one of those people who shield their children from absolutely everything so they can go out in the world later and be overwhelmed by reality, then skip the flick. It's not at all bad, really.
There's food on level three. It's not too unreasonable, considering. There's also a gift shop. It's real big and fulla neat stuff; and T-shirts cost thirty-six bucks. CD's aren't that overpriced. Lotsa books and trinket things, too. I went into shock after seeing a T-shirt price tag and don't remember much else, so that about wraps up the old review.
