Altermodern is the new YBA. Beware.
(And by the way: declaring that “post-modernism is dead” makes little sense; po-mo was, among other things, when we became skeptical about metanarratives - periodization and the Zeitgeist being clear examples. In other words: post-modernism is when you realise that the avant-garde artist arguing that the current style is dead and must be replaced by the kind of stuff he makes - for such are the times, so dictates History - is just silly.)
