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" earned the singer mainstream attention, culminating with the fall 2019 release of her self-titled debut mixtape. She further honed her sound with her 2021 full-length studio album Troubled Paradise. A native of the St. Louis 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. The song "Mine" arrived in early 2019 and went viral, reaching several digital pop music charts. She supported "Mine" with a tour dubbed "The Mini Tour," leading up to the released of her debut mixtape, Slayyyter, that September. In June 2021, she returned with her full-length debut studio album, Troubled Paradise, which featured a more polished pop production via a handful of producers, including Wuki, Gupi, Zakk Cervini, and others.
