HexD is a microgenre that originated in the late 2010s, pioneered by the music collective Hexcastcrew. The genre is characterized by its bitcrushed lo-bit sound, sometimes drawing inspiration from Nightcore by speeding up and high pitching songs, especially through remixes and samples.[1][2] It typically encompasses atypical examples of cloud rap or trance music. It began to take on more prominence when one of the members of Hexcastcrew, Stacy Minajj, released his DJ Mix Rare RCB hexD.mp3 in June 2019.[3] HexD music can be split in two branches based on their influences: Surge (also known as Crushed Trap), which is the original hip-hop and cloud rap-oriented musical style, and Sextrance (also known as Crushed Trance), a more recent derivative genre associated with trance music and other subgenres of electronic dance music. The visual style associated with HexD is generally used on cover arts and music videos, focusing on a low-quality, dirty and melancholic aesthetic that evokes nostalgia, mainly for the mid-to-late 2000s. It incorporates heavily edited and compressed images, photos of (primarily) female anime characters, references to 2000s gaming culture, symbols such as the Star of David or demonic sigils, and inspiration from styles and subcultures like Emo, Scene, Blingee, and Frutiger Aero. Closely related microgenres with a very similar aesthetic include Sigilkore, Xpiritualism, and Krushclub (all of which might aesthetically or musically overlap with each other to some extent).
