RIKA, also known as Erica Kim, is a Korean American alternative R&B artist from the Bay Area, California. RIKA had been making music and uploading it onto the internet since early 2019.

She first began gaining popularity, however, not for her music but for her content on TikTok and Instagram later in the same year. In November of 2020, she became well known for her viral K-Pop audition video on YouTube. This positive traction inspired her to pursue becoming a professional musician.

She is recognized for her seamless blending of languages and her narrative approach to writing lyrics.
