In November 2004, the duo released their fifth and last studio album under SM Entertainment, "Gravity". The album received little promotion, and became the duo's lowest-selling studio album, selling just below 90,000 copies. Nevertheless, they held their first official concert successfully in Jamsil Arena on December 21, 2004, and received "Best R&B Artist" award from SBS Gayo Daejun. A controversy rose as critics questioned their eligibility for the award, because the album was released only two months before the show. They challenged the credibility and fairness of SBS Gayo Daejun in its entirety as the artists who boycotted SBS such as YG Family or those who were not present did not receive any awards. They scorned the show as "a party for only those who were present."
