Park Se Yoon (born October 16, 1989, Seoul), professionally known as Crucial Star, is South Korean rapper and debuted with a nine track mini-album, titled “A Star Goes Up“. The album features big named artists like Basick, Dok2, Kebee, The Quiett, and many more.

Crucial Star segued into the hip-hop music scene at the age of 17, performed in a group titled “Libra Twins“, and eventually tried out (and won) to become the first open-audition musician to land a deal with the Korean hip-hop label, Soul Company.

Since then, he’s worked on material for other label mates, as well as releasing two digital singles of his own: “Crucial Star vs Mad Clown” (in collaboration with Mad Clown of the same label) and “Catch Me If You Can“.

Crucial Star structures his raps around stomping beats and has a delivery very similar to that of Kid Cudi, Drake, and a handful of other American rappers. In fact, Crucial Star has mentioned that he’s strongly influenced by their musicality and vocal arrangements.
