Doctrine is the sixth studio album by Dutch death metal band Pestilence, which was released on April 24, 2011.
[1] The album was recorded and mixed at Woodshed Studio in southern Germany with engineer Victor "V.Santura" Bullok.
The album represents a second release by the reformed Pestilence, with two new members: Yuma van Eekelen and Jeroen Paul Thesseling, who was a member of the band during the Spheres era.
Technically, the album is an experimentation with very low tunings, with Mameli and Uterwijk playing on 8-string guitars with standard tuning, and Thesseling playing a 7-string fretless bass tuned in F#.
The album has received mixed reviews, with much of the criticism pointed to the album's down tuned guitar sound, as well as Patrick Mameli's vocals.
