In 2006, she joined the hip-hop group Uptown, featuring on their album ‘Testimony’ as a replacement for the original vocalist. Following a brief hiatus, Jessi returned in January 2009 with her second single album, ‘The Rebirth.’ A pivotal moment arrived in 2014 when she joined the hip-hop trio Lucky J under YMC Entertainment, debuting with the digital single ‘Can You Hear Me.’ Her breakthrough came in 2015 as the runner-up on Mnet’s hip-hop competition show ‘Unpretty Rapstar,’ which catapulted her into mainstream popularity. That same year, she was featured on J.Y.
Jessi signed with More Vision in 2023, releasing the single ‘Gum’ before her departure in 2024. Demonstrating her entrepreneurial spirit, she was featured in the Apple TV+ documentary series ‘K-Pop Idols’ in 2024 and launched her independent label, UNNI, in September 2024. Concurrently, she signed a management contract with DOD Entertainment, although this agreement was later terminated in October 2024, signaling Jessi’s continued evolution as both an artist and an independent creative force.
