Jeong Sa Gang, also known professionally as Peak, is a South Korean singer, former member of TheEastLight (더 이스트라이트) and current member of duo PEAK & PITCH (피크엔피치). He graduated from Seocho High School, and he first appeared on TV in 2013 when he was part of "The Voice Kids Korea" and was selected by Highlight's Yang Yo Seob. He also appeared in "Superstar K3".

He made his debut in November 2016 as TheEastLight's rapper and vocalist with their first single, "Holla". However, on October 18, 2018, controversy emerged when media outlets began reporting allegations of physical and mental abuse against the group members by producer Moon Jung Il and with the CEO of Media Line Entertainment (미디어라인 엔터테인먼트), Kim Chang Hwan, present during most attacks and doing nothing to stop them. The next day, group leader Lee Seok Cheol confirmed the allegations on behalf of himself and his brother and group mate Lee Seung Hyun. Both were immediately separated from the group.

The agency issued an apology but denied the allegations. On October 22, 2018, his contract was terminated, and the group officially disbanded. In late December, he attended (alongside Lee Eun Sung) a press conference by CEO Kim denying all charges which further divided the group members. CEO Kim and producer Moon were indicted on charges of child abuse in January 2019.

In 2020, he joined Peak Entertainment (피크 엔터테인먼트) and re-debuted as part of PEAK & PITCH in August 2021 with their first digital single, "Iko Iko".
