Originally released in 1972, Octopus is Gentle Giant's fourth album, and featured band members: Gary Green (guitars, percussion), Kerry Minnear (keyboards, vibraphone, percussion, cello, vocals), Derek Shulman (vocals, alto saxophone), Phil Shulman (saxophones, trumpet, mellophone, vocals), Ray Shulman (bass violin, guitar, percussion, vocals) and John Weathers (drums, percussion, xylophone). The album was produced by the band and engineered and mixed by Martin Rushent. For this new edition, Steven Wilson tastefully remixed the album as well as a bonus mix of 15-minute concert performances of "Excerpts from Octopus" from the band's 1976 tour. New sketches by Roger Dean (who produced the original UK album cover) will be included in the new packaging as well as artwork from the USA album (an octopus in a jar created by Charles White).
