Kang Young-hyun

Kang Young-hyun (; born December 19, 1993), known professionally as Young K , is a South Korean musician, singer, songwriter, and rapper. He is best known as the bassist and vocalist of South Korean pop rock band Day6.

Early life Kang Younghyun was born on December 19, 1993, in Seoul, South Korea as an only child. He was raised in Ilsan, South Korea and moved to Toronto, Canada. He attended St. Andrew’s Middle School, followed by York Mills Collegiate Institute. Since sixth grade, he has not lived with his parents. During this time, he went by his English name, Brian Kang. Kang moved to Korea in 2010 and became a trainee at JYP Entertainment (JYP). After he signed a contract with JYP, his father retired and moved to Toronto with his mother. On October 5, 2017, he received his bachelor's degree in Business Administration from Dongguk University while working on his band career. He graduated from university on August 23, 2018.

Career 2010–2015: Pre-debut While attending middle and high school in Canada, Kang began his musical journey and career by forming two bands with his best friends Terry He and Don Lee. Their first band was called 3rd Degree. Their second band, Kiss Me Ever So Softly (KMESS), included two other close friends: Sean Yerzy and Sonny Tsai. The group posted several viral music videos and vlogs on He's YouTube channel and performed at various local competitions and shows (including several shows organized by A1 Radio, a subsidiary of Sing Tao News Corporation), which helped them garner a fanbase and attention from record labels and managers.

In the summer of 2010, after noticing Kang from his entry to JYP's Global Audition program and YouTube work, JYP Entertainment staff met with Kang and his bandmates in Toronto for an audition. Young K went on to appear in the fourth episode of WIN: Who is Next? as a part of JYP's rapping team with Got7's Mark Tuan and Jackson Wang against the combined rapping teams of Team A and Team B, where he became known for the verse, "YG, get an attitude!" He was also a part of JYP's vocalist team alongside his eventual Day6 bandmates Junhyeok, Jae, Sungjin and Wonpil.

In 2014, Kang was selected as a member of five-member rock band 5Live under JYP, but their debut was cancelled. The band was reformed as Day6 after the addition of drummer Dowoon in 2015. Kang was also originally selected as a member of the group Got7, but was ultimately cut from the lineup.
