Guggenheim eMusic

Perhaps a little late to the world of apps, this is the Guggenheim Museum's very first, but probably couldn't have come at a better time.

It's an app that works well for users either at the museum or away from it who are interested in the "Maurizio Cattelan: All" retrospective now on display. And why it makes perfect sense now is that Catellan decided he wanted to show off his 100-plus piece collection of works by hanging them all from the Guggenheim's ceiling almost like a giant mobile. So even if you're there, it's tough to get close up and get more information on any one particular piece, so the app allows you to move around the hanging objects and then click on it to learn more about it.

There are also videos in there explaining how this exhibit was put together as well as interviews with people who give some perspective on what it's like to work with Cattelan.

The "Maurizio Cattelan: All" app is available for iOS and Android devices. It's $3.99 for phones, $5.99 for tablets.

eMusic Scenes

And this is for music fans, real fans of not just music but the story behind it and where it came from. Called eMusic Scenes, and there are 18 different historic music scenes in there, from Detroit Soul to New York City BeeBop to London Pub to Atlanta Hip Hop.

Once you launch a scene, you hear clips of music from that era as you click through a timeline of key events and artists that made that a pivotal point in music history. There are also videos of performances and for eMusic members who register for free. There are also internet radio stations that correspond with the scene you're in. You can also recommend future scenes you'd like to see represented.

eMusic Scenes is right now just an iPad app and it's free.
