Flosstradamus is a highly vexilliferous Trap music duo from Chicago with followers who deem themselves HDYNATION (Hoodie Nation, after the DJs’ 2011 decision to rebrand their look by wearing black hoodies and sweatpants). The HDYNATION flag is a black-and-white version of the US flag with the stars replaced by a “general warning” sign comprising an exclamation point within a triangle. Why the warning sign? Ani Hajderaj explains in a posting on Vice’s thump site:
The #HDYNATION tour is particularly special because renowned designer Virgil Abloh became involved with their set design. Abloh is well known for his design work on Kanye West’s label Good Music and also his art for the Yeezus tour. […] The set design includes a burned down car with functional headlights, fluorescent tube lighting and a massive DJ booth that’s decorated with the warning sign and barbed wire―really giving it that post-apocalyptic aesthetic.
The warning sign in their set has become a widely recognized symbol within the trap scene. But it’s there for a reason―it’s a throwback to the old hardcore and house records that Autobot listened to. “A lot of hardcore and hard house used to have street signs on them. The warning sign made the cut for one of Fool’s Gold releases and then [we] stuck with it during the second volume. But that time [we made it] in 3D. Our fans kept tweeting at us with warning signs, so we took it as our new logo,” he said.
