Steven Wilson’s new stereo and 5.1 surround sound mixes of Jethro Tull’s Thick As A Brick were originally included on the album’s 40th Anniversary Edition, released in November 2012.

For the 50th anniversary, a new vinyl pressing of the Steven Wilson remix, mastered at half speed, was released with the original newspaper cover. The CD/DVD bookset was also reissued, still titled 40th Anniversary Edition, but with the mastering on all versions of the remix as originally intended by Steven Wilson. It can be differentiated from the original pressing by the copyright dates on the back and by being released on Parlophone instead of EMI.
