The 1975 title was their last album to feature the early 70s lineup of Ian Anderson, Martin Barre, John Evan, Barriemore Barlow and Jeffrey Hammond-Hammond.

It's been remixed by Steven Wilson and includes seven bonus tracks, a full concert mixed by Jakko Jakszyk and live footage shot in Paris in 1975. It's presented in a casebound book and comes with 80 pages of background history and notes by Anderson.
