Beast returns in autumn with their third mini-album 'Mastermind'. The powerful titular opening track 'Mastermind' sets the tone with heavy beats and dramatic strings. The album's main track 'Breath' is composed by frequent collaborator Shinsadong Tiger and Choi Kyu Sung, with lyrics by member Jun Hyung. Another sought-after hitmaker Super Changttai, the composer of 2PM's 'I Hate You' and 'Tired of Waiting', was brought on for V.I.U (Very Important You). The album also includes 'Clenching a Tight Fist', a soft ballad that contrasts with their usual style.
