Theory In Practice, a Swedish progressive and death metal band, was formed in 1995 in Sandviken and consisted of Peter Lake on guitar, Matthias Engstrand on bass and keyboards, Henrik Ohlsson on drums, and Johan Ekman as the vocalist. Their first demo, Submissive (1996), recorded in May 1996 at Abyss Studio, garnered underground attention and secured a deal with Pulverised Records. The band's debut album, Third Eye Function, was released in 1997, followed by Ekman’s departure to pursue music studies. Ohlsson took over vocal duties for the subsequent release, The Armageddon Theories (1999). Theory In Practice then signed with Listenable Records and released their third studio album, Colonizing the Sun, in 2002. The band entered an extended hiatus shortly after.
