[4] Park began rapping when he was fourteen years old, inspired in part by the rappers he saw perform weekly at Project Blowed, a local open-microphone workshop.

[12] He has also collaborated with Epik High, Traphik, Wax, Jay Park, Kahi, Jessi, GSoul, MC Jin, Year of the Ox, Rekstizzy, and Anderson .Paak.

[16] He has been featured on NBC for his viral video Jam Session 2.0, consisting of eight different musicians from around the world sharing the spotlight individually via split screen but collaborating on one cohesive track.

[23] In 2016, he released the music video "Safe," [24] which gained widespread attention for superimposing Park's likeness onto the faces of white actors in famous movie scenes.

"[26] Park was also a starring member of the 2016 documentary Bad Rap, which outlined the lives of four East Asian American musicians trying to make it in the hip-hop scene.
