All-Star, a dynamic male duo known as 올스타 in Korean and オールスター in Japanese, broke the K-pop scene when they debuted with the smash hit "Sugar" on August 1st, 2015. Originally a five-member group, All-Star's lineup eventually slimmed down to just Noah and Joonhyeon. Despite their short-lived run as a duo, All-Star left a lasting impact on the K-pop world before ultimately disbanding in 2017.
