“The purest black-metal artist is one who’s unknown and inaccessible,” said Nicola Masciandaro, a professor of medieval literature at Brooklyn College who organized the six-hour event.

In a way, black metal runs on a very old cultural motor: loss of faith, and the hysterical fear and sadness that come with it. But it has become one of rock’s best modes of resistance, which is why it persists, why recent books and films about it have found an audience (like Peter Beste’s photo essay “True Norwegian Black Metal” and the documentary “Until the Light Takes Us”) and why it has inspired a new American wave of bands, including Nachtmystium, Krallice, Wolves in the Throne Room and Liturgy.

Even as the Americans bend black metal far away from tribalism, violence or antireligious malevolence (some Norwegian black-metal musicians became notorious for murder and church burnings) and toward something more Whitman-esque, it remains ingrown. Some of its practitioners  like the Americans Xasthur and Leviathan  make records but will not perform or, in Leviathan’s case, give interviews. Talking about black metal in certain quarters seems deeply lame.

One commenter on the online-forum page of the metal magazine Decibel summed up a certain kind of black-metal fan’s attitude toward the symposium. This music, the contributor wrote, “has nothing to do with being intellectual and everything to do with not wanting to try and break every little thing apart” for analysis.

“There’s lots of resentment toward a sensible discourse around black metal,” said Mr. Masciandaro in an interview. “There’s also lots of dissent and difference around what black metal is. Its center of gravity is an essential negativity, an idea of some remainder, something that cannot be reduced.” He was inspired to organize the symposium, he said, by the conference on heavy metal, held last year in Salzburg, Austria, organized by Mr. Scott. He was there and wanted to create a more specific event. He chose a club with a bar as the setting, rather than a university, figuring it would be more “ludic.”
