As One 是韩国歌坛唯一的“HIP HOP-R&B”二人女子组合,两人四年前成为好朋友,早已培养出绝佳的默契,因此便把组合命名为 As One。As One 的实力最早在“感觉1999合集专辑”中崭露头角,一首《I’ll Never Been ToMe》招来众多垂询,...As One 是韩国歌坛唯一的“HIP HOP-R&B”二人女子组合,两人四年前成为好朋友,早已培养出绝佳的默契,因此便把组合命名为 As One。As One 的实力最早在“感觉1999合集专辑”中崭露头角,一首《I’ll Never Been ToMe》招来众多垂询,于是在2000年11月发行了单曲。这张《Day By Day》是 As One 的第一张专辑,成名曲《不让你知道》,前三周电台点播率就爬升至冠军,专辑一天至少狂卖一千张,确实惊人。首张专辑《Day By Day》三个月的销售是十万张,为了纪念这个好开始。特别发行《ONE+ONE》版,目前也破了十万张的销量。接下来发行的单曲如《爱的Plus!》的成绩也不遑多让。展开更多
