Biography
Park Se-yoon was born on October 16, 1989, in Seoul, South Korea. His father is the painter Hang-Ryul Park.

He made his musical debut at the age of seventeen in the hip hop group Libra Twins. Several years later, he signed with independent hip hop label Soul Company, working under the name Crucial Star. He and label mate Mad Clown collaborated on the digital album Mad Clown VS Crucial Star in 2010. The following year, he released his first EP, A Star Goes Up, and his first full-length album, A Star From The Basement.

Following the dissolution of Soul Company in 2012, Crucial Star moved to Grandline Entertainment. While with Grandline, he released two mix tapes, Drawing #1: A Dream Spokesman (2012) and Drawing 2: A Better Man (2013), two albums, FALL (2012) and Midnight (2014), and one EP, Boyhood (2015).

In 2015 he appeared as a contestant on Mnet television rap contest Show Me the Money 4. He was eliminated in the preliminary round after forgetting his lyrics. In October 2015, Crucial Star's agency published a statement announcing that he and Unpretty Rapstar 2 contestant Heize were in a relationship. A week after this announcement, it was reported that they had broken up several months prior.

He left Grandline Entertainment in January 2016 when his contract ended. In April, he signed with C-JeS Entertainment.

Pstyl2와 함께한 듀오 리브라트윈스의 앨범 《Good by my lady》를 통해 힙합 씬에 등장했다. 당시 Soul Connection의 새 멤버 Jepp Blackman의 참여로 소울 커넥션이 유명세를 얻은 후 화제가 되기도 하였다. 정식 데뷔는 싱글 [《Catch Me If U Can》으로 하였다. 이후에 소울 컴퍼니에서 EP 두 장과 다수의 싱글 앨범을 발매한 뒤에 그랜드라인 엔터테인먼트에서 믹스테입 2장과 소품집 《FALL》을 발매하였다.
현재는 그랜드라인 엔터테인먼트와 계약이 끝난 상태로 씨제스 엔터테인먼트와 새계약을 맺었다. 그러나 2017년 중반에 씨제스 엔터테인먼트와 계약을 해지하고, VAKER라는 1인 기획사를 설립하였다, 이후 사명을 스태리나잇뮤직으로 변경하였으며 윈과 디너프를 영입하면서 1인 기획사에서 정식 레이블로 전환하였다.
