ALL'N, a classically trained violinist turned K-pop artist, has been named Billboard's K-Pop Up & Comer of the Month for August, with the outlet publishing an exclusive photoshoot and interview. Having previously won international violin competitions and served as a concertmaster and soloist with orchestras, he moved into K-pop after realising the genre offered a fuller form of expression, one combining performance, individuality and fandom rather than music alone.

He describes his sound as "violin-driven K-pop," weaving the instrument into rap, vocals and choreography from his debut single "We Up" onward, with the violin's role shifting between lead hook and emotional support depending on the track. His stage name blends "all in," reflecting his commitment to the craft, with "olin," a nod to the violin, and he cites EXO's "Growl" and violinist Henry Lau as early influences that drew him towards K-pop.
