I've always found the whole museum situation in Berlin a tad confusing.

All major museums in Berlin fall under the “Staatliches Museen zu Berlin” umbrella. To make it more complicated, there’s also the Nationalgalerie of which the Neue Nationalgalerie is a part of. The collection of the Nationalgalerie is on show at five different locations, besides the Neue Nationalgalerie, there is also the Alte Nationalgalerie, the Friedrichswedersche Kirche, Museum Berggruen, Sammling Scharf-Gerstenberg and Hamburgerbahnhof. Are you still with me? 

Technically the Neue Nationalgalerie is your go-to museum for the collection’s 20th century art, but then again, the Hamburgerbahnhof has stuff from that era as wel. I recommend to just visit allll of the museums Berlin has to offer.

Anyway, cool thing about the Neue Nationalgalerie is that it’s designed by German-American Bauhaus architect Mies van der Rohe, pioneer of modernist architecture. He was all about simplicity, fluid open spaces and called his work "skin and bones" architecture. If you look at the museum, it’s easy to see why. At first glance, it seems to be empty. Really, you can look right through the building! 1968 was a special year, the Neue Nationalgalerie opened its doors and that same year the band Kraftwerk was founded. If you've never heard of them, they're the whole (sole?) reason bands like Daft Punk exist today. Years later, right before the museum closed for renovation, the German electronic music pioneers kicked off their 2015 tour at the museum. The band collaborated with other artists to make 3-D videos that where projected inside the museum while the band performed their music. I'm pretty sure that must have been the coolest show EVER.
