Charles Duncan Green V (born May 10, 1999), better known professionally as CG5, is an American singer-songwriter, music producer, and YouTuber. He is well known for making nerdcore hip-hop songs about various topics relating to video games and internet culture. He is also the director of the horror series and film hybrid Project U Move.
Charles Duncan Green V was born on May 10, 1999, in Phoenix, Arizona. Green has three siblings and is the fifth generation of his name in the family. Green started making music when he was five years old, using software on his father's computer.' Green and his family moved to Arizona when he was 12 years old, transferring throughout multiple high schools until he graduated from Highland High School in Gilbert, Arizona. Green was a member of a church choir, and took a radio/audio production class while in high school. Green additionally worked as a front counter at Chick-fil-A. He would later pursue music full time after graduating high school.
Green started posting on YouTube under his name in mid 2012, releasing his first original song, "What Is A Dream". Green continued releasing original and cover songs on SoundCloud and YouTube. In 2014, he released his first extended play on SoundCloud, Celadon.
Green created CG5, his current channel, in October 2014 and initially released remixes of popular songs and video game soundtracks on the channel. In 2015, he released his second extended play, Turning Gray. The name for the channel was chosen because he is the 5th generation Charlie Green in his family.
At this time, Green decided to stop posting on his old channel in favor of his new channel, CG5, after his recent songs that were posted on the new channel went viral and gained millions of views, and at the same time decided to pursue posting on the channel under the nerdcore hip-hop genre. Around the same time, he renamed one of his channels from "CHARLES" to "CG5LIVE", while also repurposing it to focus on behind-the-scenes videos of songs, non-music content, and edited-down videos of his live streams.
In March 2020, Green released his debut album, "Patiently". In September 2020, Green released his single, "Show Yourself", based on the video game, Among Us, which reached over 100 million views on YouTube.
On July 1, 2022, Green sang the USA National Anthem for the Red Sox in the Wrigley Field. On January 27, 2023, Green collaborated with artist LeGrand, re-releasing his single, "give a little". The song became popular on TikTok, from a remixed line by Green.
At this time, Green faced major negative attention because of his songs, referring to them as unfunny and ruining the subject material. Green stated that the negativity towards his songs significantly affected his mental health, claiming it to be forced and overly exaggerated. In June 2023, Green released his single "GRIMACE", based on the Grimace Shake trend. In July 2023, Green released his single "THX", based on the web series Skibidi Toilet.
On May 10, 2024, Green's birthday, he released his single "Forbidden Feeling", which is a song about his relationship anxiety. The song was well-received, with Jonathan Currinn of Good Star Vibes saying, "He has flawlessly created poetic and artistic lines that elevate this song to a whole new level."
In January 2025, Green announced the analog horror series, Project U Move. The series features child actor Piper Rubio, who is known for her role in Five Nights at Freddy's, alongside cameos from fellow YouTubers and music artists.
In March 2025, during the 2025 Game Developers Conference, Universal Music Group revealed that they launched an initiative with Green and rapper Lil Wayne for a collaboration with motion capture library Heat, which implemented licensed songs from both musicians as well as their respective emotes. Green's songs included "I See a Dreamer", "Sleep Well", "Let Me In", and "Dancin'", among others.
Green has performed multiple tours worldwide, most notably in the United States, United Kingdom, Ireland, Netherlands and Australia. In 2025, Green performed his US leg tour "Too Many Songs", with each show having at least 50 songs from his discography sung.
