Jonathan Park (Hangul박성만; RRPark Seong-man; born February 18, 1986), known professionally as Dumbfoundead, is an American rapper of Korean descent. He originates from the Koreatown neighbourhood of Los Angeles, California.

Early life

Born in Buenos Aires, Argentina to South Korean immigrants, Jonathan Park (Korean name: 박성만 Park Seong-man) was smuggled in along with his sister by his mother to Mexico, and then later settled in Koreatown in Los Angeles at the age of three. He was often seen as a class clown by his peers at an early age, and was exposed to hip-hop at age ten upon entering a community centre in MacArthur Park and meeting emcees such as Mark Luv of Zulu Nation, Poppin' Chuck, Cre8 RTN, and Ezrock. This first experience with hip-hop allowed him to develop the technique of freestyling and to educate himself on hip-hop's history and roots. A year later, he was taken to Project Blowed, an open-mic workshop located in Leimert Park in South Central Los Angeles, by a high school friend. There he would continue to perfect his abilities as an emcee amongst the influence of "Blowdians" such as Otherwize, Riddlore, Nocando, P.E.A.C.E., and a large number of others, eventually earning the title of "Blowdian" himself.

Park dropped out of John Marshall High School in his sophomore year, as a result of frequent truancy. After dropping out, Park moved into a one-bedroom flat in the MacArthur Park area with his sister. Prior to initiating a full-time professional music career, he worked as a bail bondsman, among a large number of additional odd jobs.


Park began growing a large web fan base, after video clips of his rap battles were posted to YouTube. In 2015, Park returned to rap battling to participate in Drake and OVO's event King of the Dot Blackout 5, and was complimented by Drake himself, who expressed his excitement in his return. Park competed against Wild 'n Out cast member Conceited, and the battle is currently the most popular English rap battle of 2015. In August 2015, Park has battled fellow battler Dizaster on Day One of KOTD's World Domination 5.

His first solo album, DFD, was released on November 1, 2011. His second album, Take the Stares, was released on October 16, 2012. In 2013, Park released his third album Old Boy Jon, and a single by the same, all produced by Duke Westlake.

Dumbfoundead has collaborated with additional music artists, including Epik High, Traphik, Wax, Jay Park, Kahi, and Anderson Paak. In 2015, he was featured on Complex's remix of Keith Ape's song It G Ma, alongside popular rappers Waka Flocka Flame, ASAP Ferg, and Father.

He has been featured on NBC for his viral video Jam Session 2.0, consisting of 8 different musicians from around the world sharing the spotlight individually via split screen but collaborating on one cohesive track. He has additionally been on Los Angeles Times, Last Call with Carson Daly, MTV Hive, and Mnet.

Park played a supporting role in Joseph Kahn's horror film Detention.
