Chase McArthur, known as Sybyr (pronounced "cyber") (formerly known as Syringe), is a rapper and producer (under the alias Landfill) from Maryland. His music is known for its dark, hard hitting, experimental & sometimes nearly deafening sound, accompanied by his gruff voice and gothic lyrics. Syringe is also known for appearing somewhat flamboyant, often wearing high heels, painting his nails, and wearing lipstick.
In mid-2017, McArthur was reported missing by many of his associates, reportedly last seen in Detroit. About a week later, it was reported that he had been found and contacted, and that he was safe. It is unknown at this time what led to his disappearance.
Sybyr is the leader of the music collective WeirdClvn/Anti-World.
