Mindslip was formed in Stockholm, Sweden, in 1999 and has since the beginning consisted of Johan Adamsson, Daniel Lundh, Andreas Lundin, Janek Hellqvist and Jaanus Kalli. Adamsson, Lundh and Lundin had been playing in bands together for years, none of which had worked out due to personal differences. Hellqvist and Kalli had been through similar experiences while playing in other bands, and were now searching for members to form a metal band. From the very first rehearsal it was apparent that there was a musical and personal chemistry between them that had not been present in any other band they had been a part of. The decision to form a new band was taken on the spot, and Mindslip was born.

Initially combining thrash and death metal, the band recorded two demos ("Dissident" and "No allegiance"). and gradually began incorporating heavier influences into their material. Dedicated to improving every aspect of their art, the band continued to push their limits musically, lyrically and as instrumentalists. In 2005, the band's dedication and hard work resulted in their fastest and most brutal recording to date, "Dead silence". By the recording of "Dead silence", Mindslip had come into their own as a full-fledged death metal outfit.
