Chase MacArthur Cauthen (born September 6, 1996), is a rapper and vocalist hailing from Prince George’s County, Maryland. Sybyr has numerous former aliases, most notably Syringe, MacXVII, and LiL NEEDLE—he also produces instrumentals as Landfill. Sybyr was one of the first artists to partake in the trap metal subgenre—often cited as the genre’s most impactful innovator—where he combined hip-hop with chaotic production and distorted vocals.
Alongside Ghostie, KiddBeatz, and the late Loboloki, Sybyr is a co-founder of the Anti-World collective—formerly WeirdCLVN and Weird Melodicians—a music collective founded upon social outsiders “expressing abnormality through music,” as Chase explained inside a September 2014 interview with GOLD BUSHIDO. In a September 2018 interview with All Def Music, Sybyr described the concept of Anti-World to be “a place where no fuckery is allowed.”
Sybyr’s clothing preferences and appearance are oftentimes met with backlash due to his defiance of gender norms. Chase can be seen sporting high-heels, lipstick, nail polish, and platform boots inside social media posts—stylistic choices that have been a cemented part of his persona since June 2016.
Sybyr’s discography is extensive, with over fifty bodies-of-work self-released since July 2012. Sybyr would publicly debut as MacXVII, releasing his fully-instrumental record, Space Trips. It would take nearly two years before Chase would experiment with vocals, releasing his loose single, “1449,” in April 2014.
On June 4, 2017, Sybyr was reported missing by many of his associates—he was last seen on June 2, 2017, inside Commerce City, Denver. On June 12, 2017, it was stated that he had been found and was safe. Unbeknownst to fans of the Maryland artist, Chase was spending time inside behavioral facilities and hospitals, which he detailed inside a September 2018 HAM Radio interview with All Def Music
Following Chase’s leave from the psychiatric ward on July 12, 2017, he decided to change his alias from Syringe to Sybhyr, first announced via a Facebook post. Chase later switched his pseudonym to Sybyr on July 16, 2017. Being homonymic with cyber, the Sybyr alias seemingly has roots from Sybyr’s childhood, where he routinely spent time on the internet.
