The long-time friends have struck a dynamic which suits them. Derian--or sometimes, "Diz"--comes off as a bizarre art-snob / fraternity-bro hybrid. He assails you with anti-feminist manifestos and "kids today.." rebellion which lends a needed touch of bar-stool to Bronish's coffee-shop aesthetic. Currently a graduate student pursuing a career as a therapist (?!), Derian's cock-rock credos [he generally finds music boring, with the exception of Guns N' Roses, which he finds transcendent] are usually extreme, frequently annoying, and occasionally pure genius.
While it's Diz who makes the Brazen Heads funny or compelling or--well--brazen, it's Bronish who actually makes it consistently listenable. His even-keeled voice-of-reason narrative is like carbon rods keeping the Brazen power-plant productive whenever Diz gets sucked into feedback loops about the importance of getting laid or yelling at liberals. A potent critical thinker, Bronish will tell you, in crisp baritone, that academic navel-gazing need not be a pejorative term. He operates with a refreshing neglect for connotative language and general understanding that opinions are more about doing the work than being right.
On his own, though, Bronish simply isn't eccentric enough to cut through the Throught Catalog-era Internet din, which is why Diz makes for the perfect co-hort. With a show title taken from an old mythology about "bronze heads" which were able to answer any question, a casual listener might say the main theme of the podcast is over-intellectualism. But ultimately, their bottom line is about emotional freedom--even if over-intellectualism is the road they usually take to get there.
I'm not sure whether or not the Heads will ever enjoy popular podcast success. They may not, due to the heavy 'NPR" nature of the podcast world so far. But at the moment, they're doing a decent job "finding their people". For more with these dudes, check out their interview on Article 25 News.
