Angel's Knock is the debut Korean language studio album (third overall) recorded by South Korean girl group AOA. It was released on January 2, 2017 by FNC Entertainment and distributed by LOEN Entertainment through digital and physical platforms.
Double title tracks, "Excuse Me" and "Bing Bing," which represent two distinctive concepts, were released and promoted simultaneously on the music programs during their comeback week. Korean versions of AOA's previous Japanese singles, "Give Me the Love" and "Oh Boy," are also included at track 8 and 9 respectively. "Excuse Me" charted at number 22 on the Gaon Digital Chart, while "Bing Bing" debuted and peaked at number 45. The album marked the group's first comeback after the departure of member Youkyung in October 2016, and their worst performing comeback since Confused. This also marks the final release with member Choa, after leaving the group on June 30, 2017.
