"Combining an unabashed love of Y2K-era pop with an arch artiness inspired by Lady Gaga and Charli XCX along with a facility for meme culture, the St. Louis-based Slayyyter broke out in 2019 with her single ""Mine."" A viral success, the effervescent ""Mine"" brought Slayyyter out of the pop underground following she'd cultivated through a series of releases on SoundCloud. ""Mine"" brought the singer mainstream attention, culminating with the fall 2019 release of her self-titled debut mixtape.
A native of the St. Louis of suburbs, Catherine Slater began writing and recording her own music while she was studying at the University of Missouri. After a year in college, she dropped out of school so she could concentrate on her music, adopting Slayyyter as her stage name. Striking up creative relationships through social media, she eventually met the Los Angeles-based Ayesha Erotica, and the pair began collaborating long distance.
Slayyyter began uploading music to SoundCloud in 2018, starting with an Ayesha Erotica collaborative single, ""BFF."" Several songs followed that year, including ""Alone"" and ""Hello Kitty,"" which was produced by Boy Sim. In early 2019, she released ""Mine,"" which went viral, reaching several digital pop music charts. She supported ""Mine"" with a tour dubbed ""The Mini Tour,"" then released the mixtape Slayyyter in September."
