In Silico is the second full-length studio album by Australian drum and bass band Pendulum, released in Australia and Europe on May 12, 2008 by Warner Music UK, and in America on May 13, 2008 by Atlantic. The album represents a change in sound from the band's debut album Hold Your Colour, away from drum and bass, incorporating more rock and electronic influences. The album peaked at #2 on the UK Albums Chart on May 18, 2008. The expression "in silico", from which the album title is derived, is used to mean "performed on computer or via computer simulation", however group member Gareth McGrillen also commented on the way it plays upon Nirvana's well-known album title 'In Utero' (meaning 'born naturally' or 'of the uterus') and thus carries extra shades of meaning related to being "born synthetically," thus explaining the album's cover motif of a baby or foetus displayed inside a circular design (likely representing a synthetic ovum), which in turn references the blend of natural and synthesised sounds of the music therein. Releases from the album include Granite, Propane Nightmares and The Other Side, released on 28 July, 2008.
Critical reception to the album has been mixed, with most of the polarization coming from Pendulum's shift from drum and bass to a more rock and pop-imbued electronic sound. Allmusic praised that "Pendulum is determined to heal the breach" between rock and electronica, however The Guardian felt that the sound was "a little dated".
The album does have a fair amount of inaudible strong language, but no Parental Advisory label has been added.
The line in "Mutiny" (In through the maze through your reflection, we enter from a terminal connection) comes from "The Terminal" on their first album Hold Your Colour.
The songs "Granite" and "Showdown" feature on the offroad game Pure.
