i used to be really into Vorticists (little British arm of Futurism) and all that sh*t and sculptures like this by Umberto Boccioni (either 1910 or 1913 i cant be bothered to check)
but now I prefer stuff with more vibrancy and character, alot of abstract expressionism and I really like Jean-Michel Basquiat recently aswell, there's already enough of that kind of thing on this thread though.
I hate Pop Art with a passion but I like subversive photo montage like this (John Heartfield 1935)
