Jonathan Robert Whitmer (born July 17, 1999), professionally known as Kxllswxtch, is a Hispanic recording artist and songwriter from Orange County, California. He is known for his screaming vocals and horror-inspired visuals often featuring knives and fighting.

Kxllswxtch began making music in 2017 and quickly gained a local following. He dropped several songs before releasing his first EP InVain on SoundCloud. He would go on to make much of his earlier music private. His Soundcloud was found by a very influential artist, Kxng, who reposted some of Kxll's first tracks and went on to make songs with him and help him shape his sound. Kxll co-headlined The Blood & Bone Tour in the Western United States during the summer of 2019. In 2020 KXLLSWXTCH joined the collective "Buffet Boys" (Now "All But 6") after his music was discovered by producer Flexatelli, who shared Kxll's music with friends Mikey The Magician and Pouya. This is when his career took off. After signing a deal with Empire in 2020, Kxllswxtch released his first official EP, the 8-track KILL!, with no guest appearances.

After relocating from Anaheim to Miami, Kxllswxtch opened up 2021 with Pouya collaborations on “Lord of the Flies” and “Burn”. Two days before Halloween 2021, Kxllswxtch released his first full-length project, DISORDER. He is was part of the Fall 2021 Blood Was Never Thick As Water National Tour in the United States with Pouya, Jasiah, and Lu. On February 17, 2023 Kxll dropped "THE WALLS HAVE EYES" with a guest appearance from Lu and production from Mikey The Magician, 7oh2, Powers Pleasant, Rocci, and more. Read more on Last.fm.
