Cube Entertainment held their first family concert on August 14th at the Seoul Jamsil Outdoor Stadium in Korea. The concert was titled “United Cube Concert: Fantasy Land” and featured Cube Entertainment’s artists 4minute, G.NA, and BEAST. At the concert A Pink, Huhgak, and Mario (A Cube Entertainment) made a special appearance to perform. There were also many special stages that the fans enjoyed.
At the concert, G.NA performed her debut track, “I’ll Back Off So You Can Live” with BEAST’s leader Doojoon as the rapper. Although the song features BEAST’s rapper Yong Junhyung, during her debut song promotions, many other artists performed the rap section live. These artists included MBLAQ’s Thunder, CN Blue’s Yonghwa, 4minute’s Hyuna, and BEAST’s Yoon Doojoon, in addition to Junhyung himself. Both Doojoon and Junhyung featured in G.NA’s music video for “I’ll Back Off So You Can Live.”
At the press conference before the United Cube Concert in Seoul on August 14th, G.NA revealed, “I honestly was not aware that Yoon Doojoon was going to be featuring in ‘I’ll Back Off So You Can Live’ at the concert this time.”
In response, Doojoon replied, “I featured for the song because I knew that Junhyung had to feature for Hyuna right after, so I took the initiative and featured for her myself.”
G.NA also performed “What I Would Do If I Had A Lover” with BEAST’s Yoseob at the concert. Although there is no video from the concert showing Doojoon’s feature in “I’ll Back Off So You Can Live.”
