Originally introduced as a Korean version of the Pussycat Dolls, After School stands out for their live performances. In one promotion cycle, the entire group learned a drum-line routine for single "Bang!," and turned to complicated tap dance for Korean track "Let’s Step Up." As electro-pop dance ballads, tracks like "Shampoo" and "Because Of You" epitomize the genre-blending of K-pop. After School was also the very first winner of the Billboard Japan award for K-Pop New Artist of the Year. With a unique graduation system that keeps the line-up changing (similar to the way the Pussycat Doll brand works), the group can stay relevant and fresh. It’s unclear if any of the current members (nine girls are in the group at press time) can speak fluent English, but with the shifting membership, if an American debut was eyed it would make sense for their label to recruit English-speaking members.
