Cube Entertainment, the record label that signed 4minute, B2ST, and G.Na, have just released their very first 'family song', titled "Fly So High". "Fly So High" is a collaboration track featuring the afore-mentioned twelve Cube Entertainment family members, now known as 'U-Cube'. It's an upbeat and addictive song that harmonizes the artists' unique talents to create the perfect feel-good summer track. While the song was in its production stages, the U-Cube family members were honest with one another, offering their experience and expertise to help each other refine their talents, as they worked more earnestly on this track than any of their previous projects. The U-Cube members will all be performing their 'Fly So High' single for the very first time at the UNITED CUBE CONCERT on August 14th. They plan to debut the song on other overseas stages, like in Japan and England. Check out U-Cube's first family song below!
