Theory of a Deadman是來自加拿大的樂隊,Tyler Connolly（主唱/吉他手）據傳聞在一次音樂會聚會上曾帶著樂隊的demo唱片給Nickelback的Chad Kroeger,之後不久兩個人就開始合作創作音樂。他們的作品之中，Invisible Man,被在2002年的成功電影“蜘蛛人”中被用作了片尾曲，Hero（一個與Kroeger合作組成的歌手Josey Scott）.在同年，Theory of a Deadman的同名專輯發布。同樣重要的Dave Brenner（吉他手），Dean Back（貝斯手）和Tim Hart（鼓手），專輯中的hook-laden，情緒化的硬核搖滾聽起來非常類似於他們樂隊 的著名投資人的樂隊-事實上，也是同樣的讓人不安。但是大強度的巡演工作量和樸素的風格幫助Theory of a Deadman擺脫了題材上的限制，這使得他們表現的更加顯眼，三人的演奏團體在之後注入了新鮮血液Brent Fitz（來自Union 和Vince Neil的樂隊），作為樂隊巡演時的鼓手。。。Theory of a Deadman(4張)
