Rock Bang has 7 years creative experience and live show strength. Words like melody and perform sing all by themselves. This album's producers are "Lin Wea-Zhe" and "Chang Zhen-Yue". "Prove of Life" is a blend of guitar rock and electronic melody that creates a new age style. "Goodbye" is a song whose sentiments create an English style love song; the beginning is filled with piano music just like a broken lover’s confused feeling. "You are happy because of me" is a folk rhyme with a sweet feeling that was written in college by Rock Bang, influenced by Paul McCartney, and is a sweet song with a lovely melody.
