In an essay on modernism and postmodernism in American poetry, David Antin quoted a passage from Allen Ginsberg's "America" and then pondered the contemporary response among "'establishment' critics" of the 1950s. How did Ginsberg's antic style strike them? From the later vantage (Antin was writing in the late 1970s) it is hard for us to remember that Ginsberg's writing seemed unliterary. The fact is that when we read Ginsberg today we assume that, whatever else his language is, it is at least literary.
Here is a rare recording: the Hatikva sung by Jewish inmates of Bergen-Belsen concentration camp on April 20, 1945. The recording, originally made by the BBC, had been lost until around 2000. It was aired in 2007 by NPR.
