"Trve kvlt". ExplanationThis is about Black Metal fans claiming the band or album in the genre is "better" if they are obscure and cult-like, the more obscure, the better (or more "kvlt"). Bonus point if the band is theistically Satanist. The exact requirements of kvltness vary depending on who you talk to, but usually involve icy, impenetrable production, black-and-white cover art, barely sold any copies and concepts drawn from black magic, Satanism, pagan myths or out-and-out nihilism.
"Black metal is just Surf Rock with distortion". ExplanationRefers to the sound when adding distortion to surf rock which happens to mimick black metal's chord progression. There is a Truth in Television element here: both genres utilise significant amount of rapid (alternating) tremolo picking: just the way surf rock and black metal do are completely different: surf rock retains the bluesy, major-scale rock character, while black metal adopted scales from Death Metal and Thrash Metal with much higher tunings. There's even an actual album called "Black Tides" by a band Kólga that actually combines elements of black metal and surf rock.
Nightmare Fuel: Has an ENTIRE page for a very good reason. In other words, it would make perfect sense to describe black metal as this in musical form.
