How about "anomalous modernity"?
With the caveat the modernity is always anomalous. It is the introduction of jarring new elements into a system. It is always uneven, ambivalent, ambiguous, fractured, weird, and intimidating. A place that modernizes later than other places (in other words, just about everywhere except a few places) will have more anomalies. That is where to study literary modernism. Why, for example, does England have a weaker literary modernism than anywhere else, with only two major writers (Woolf and Lawrence)? One writer from St. Louis went there and pretended to be British, but let's not count him.
