20th Century Art Movements:

Expressionism:
Expressionism was a modernist movement which origintaed in Weimar Germany (post WW1). This period was when Germany had no money and no nothing due to inflation going of the scale.
The artists next paintings during this period, focused on sharp angles and shadows highlighting the darker side. Some say these reflect the depressed phsychological nature of each and every member of the country during this hard finanical breakdown and turmoil.


The other side:
'Capturing the other'
This theory is used with mirror/doors/windows etc, to put into perspective that when looking into a reflection you do not actually see the person, you see another side of a person.
An example that represents this is; 'Red Hot Chilli Peppers - 'Otherside'

Surrealism:

Surrealism is a cultural movement that began in the 1920s, where it was its most popular in France and Spain. It is recognised for its visual artworks and writings. Surrealist work juxtaposes unexpected objects/things that create an element of supprise.
e.g. the fish are in the sky juxtaposed to the sky in the bowl. They are swapped.

Pop Art:
Pop art emerged in the 1950s in Britian. Pop art presented a challenge to stereotypical traditons of art and classical subjects. This is due to material being visually removed from its known context and combined with un-relevant material. Pop art includes most its subjects from comtempory culture and presents them in a gimiky comic book style.
An example of a pop art music promo video would be; 'Beyonce - Countdown'
