''In Absentia'' is the seventh studio album by British progressive rock band Porcupine Tree (Richard Barbieri, Colin Edwin, Gavin Harrison, Steven Wilson), first released on 24 September 2002. It was their first release on a major record label, Lava Records. It is Metal Storm's number 3 of the Top 20 albums of 2002 and number 42 on the Top 100 albums of all time. This album also marked the arrival of Gavin Harrison, who replaced Chris Maitland as their drummer/percussionist.

The album is also the first to have a heavier and more metal feel, through a transition from general psychedelic rock and trance. - Wikipedia
