Jun Sung Ahn

On July 30, he performed BTS' "Save Me" at KCON LA's pre-show at the Staples Center before larger acts I.O.I, DEAN, Amber, GFriend, Block B, Turbo, and SHINee, and held a "meet-and-greet" at the convention. On August 4, 2016, while reporting chart news, Billboard's Trevor Anderson mentioned his performance at KCON LA and his nearly 1 million YouTube subscribers. Anderson accounted his Twitter posting of the popular cover of BTS' "Butterfly" for boosting the song to a re-entry on the Billboard Twitter Top Tracks Chart at Number 2, along with a cover by singer Lucia.

On August 2, 2015, he performed with opening acts at the Staples Center at KCON LA, preceding K-pop acts Red Velvet, AOA, Block B, Zion.T, Crush and Shinhwa. On August 8, 2015, he opened for the first KCON New York for VIXX, AOA, Teen Top and Girls' Generation.

On August 9, 2014, he was a special guest at KCON LA's convention, and performed at the Los Angeles Memorial Sports Arena as one of the opening acts for idols VIXX, IU, B1A4, Teen Top and G-Dragon; a violin cover of Taeyang's "Eyes, Nose, Lips" and a dance cover of BEAST's "Good Luck".

Ahn performed on the main stage at California food festival 626 Night Market on August 16, 2014 along with musician Joseph Vincent.

On October 12, 2014, his music career and Korean heritage were featured on Epicurious "Community Table" by contributors Malek Shaparak and Anne Goetz, with a recipe called "Good Luck Tomato Kimchi Soup."

By the fall of 2014, during his senior year at Northwestern University, he had more than 500,000 YouTube subscribers, over 7 million individual views and his most popular video, a cover of "Let It Go" had more than 3.8 million views. Also, in November, Asia Pacific Arts' Mai Nguyen said his Taylor Swift cover of Shake It Off "...remakes the music video with his own twist. While playing the upbeat pop song on his violin, Jun Sung shows off his comedic side in his attempts to perform martial arts and Indian dance".

On September 13, 2013, he reported as an MNET America intern.

In March he was a guest participant at the inaugural KCON Mexico festival on the 17–18, which had an attendance of 33,000. On March 16, Ahn featured in a skit titled "My K-Pop Boyfriend" by Wong Fu Productions, acting in his Boys Generally Asian persona Jeungri. On March 24, he appeared in a second BGA YouTube K-pop parody video release, "Who's It Gonna Be", which received over six million views within a few days.

Later at college, although he majored in radio/TV/film, and not music, he still joined Northwestern University's orchestra and participated in the Asian-concentrated dance crew, 'Refresh'. By his sophomore year in 2012, he no longer studied violin formally, but continued to play, and described himself as a mediocre pianist and a beginning guitarist.

On July 7, 2012, he won the annual Kollaboration Chicago award with a performance that combined violin and the Chinese yo-yo, and later competed at the Kollaboration Star Finale in Los Angeles in the fall of the same year. Also, in July 2012, his dance and violin cover of Psy’s "Gangnam Style", which he published a few weeks after the original, soon reached more than 2.4 million views, and won first place in a competition Psy held in South Korea. He 'cloned' himself in the video to appear dancing and playing the violin at the same time.

He has described his violin style as "slightly playful", because of the enjoyment he has as he plays and listens to music, hoping to share the same with his audience. In 2012, he said because he covers many vocal songs, he tries to use his violin to bring out the same human feel and tones, listening to the song for a few days and playing by ear as he practices for the final recording. Rather than creating a "perfect" music, he finds it important to include his personal feelings and emotions to create a story with the music, that his audience identifies as his own.

In July 2011, he started recording and publishing violin covers of pop songs on YouTube, under the pseudonym Jun Curry Ahn, with the "Curry" middle name being a play on his ethnicity. In about sixteen months, he had 17 million views and 130,000 subscribers, with covers including Adele's "Skyfall", Taylor Swift's "Red", Bad Meets Evil's "Lighters" and Lil Wayne's "How to Love". He has collaborated with other YouTube artists such as Arden Cho and Sungha Jung, and with his university's dance crew Refresh for a vocal, dance and violin cover of Big Bang’s, "Blue".
