Porcupine Tree

English progressive rock band founded in 1987 by Steven Wilson in Hemel Hempstead, Hertfordshire, U.K. Originally a pseudonym for Wilson's solo recordings, in 1993 the project mutated into a full band with the inclusion of Colin Edwin, Chris Maitland and Richard Barbieri. Maitland was replaced by Gavin Harrison in 2002 and the line-up remained the same until 2010, when the band went on hiatus.

On November 1st 2021 the band officially returned as a three-piece line-up, comprising Wilson, Barbieri and Harrison, with the new single release "Harridan". The band's eleventh studio album Closure / Continuation, their first in thirteen years, was released on June 24th 2022.
