Sadman Institute was founded in May 2005 in Cracow when Marcin Grabda (bass guitar), Tomasz Gurgul (electric guitar), Pawel Szczepanski (electric guitar) and Marcin Szalajko (drums) decided to play together.
During the first year the band was rehearsing, composing new songs and looking for a vocalist. This search came to an end in April 2006, when Maciej Pawlik (vocals) joined SI and the final line-up was formed. In November 2006 the band recorded their first demo album in Studio Centrum in Cracow. After these recordings, Sadman started to give concerts. At the beginning of 2008 the band went through line-up change - original drummer Marcin Szalajko was replaced by Maciej Berniak. A year later another line-up change took place - Marcin Grabda was replaced by Filip Malinowski.
