Condition: Not sealed
Mastermind is the third mini-album by South Korean boy band Beast, and was released by Cube Entertainment on September 30, 2010. The lead single "Soom" is composed by Shinsadong Tiger and Choi Gyusung with lyrics written by both the composers, Rado and member Yong Junhyung. The song "Break Down" is created by Lim Sanghyuk and Lee Joohyung.
The song "Mastermind", just like the title of the album, served as the intro track with the word meaning, “someone who can control other object with ease.” It has the hidden meaning of Beast wanting to remove the rookie image and state of the public that they want to show their own style of music.
