Double-A (Korean: 더블에이; pronounced “Double-A”), stylized as “AA”, was a South Korean boy band formed by Wellmade Yedang formerly known as Well Made STAR M in 2011. The group consists of two members: Woosang and Hoik. Since 2015, Blue Star was acquired by Wellmade Yedang, the group while managed by Blue Star.
Aoora was the first to join the group. Looking for a company he could work with and make music he decided on Well Made STAR M.

The company then later added Juwon and Hoik, who had aspirations to be singers and moved from Busan to Seoul to do so, and Kimchi, who had quit learning the piano and clarinet to his dream of becoming a singer.
The song “So Crazy” and its music video earned them much critical acclaim, with their debut marked as “sexy and charismatic”. Despite Aoora being the oldest, Woosang became leader.
