Two Yoons (Heo Ga Yoon and Jeon Ji Yoon) is a subgroup of the Korean girl group 4 Minute who had their debut with the single “Harvest Moon” last January.
Two Yoons have another song entitled“24/7” which was appreciated by Koreans and foreigners. They received many positive feed backs for their daring experiment. It's bold because the song is a dance number based on country music--- the first in K-pop history.
The well-known American magazine Spin complimented the song for giving country music a different flavor. The magazine called it as “Kountry” (meaning the country genre of K-pop).
