Since Ian Anderson has been talking about this, I guess it’s now official. I recently completed a brand new mix of Jethro Tull’s “Aqualung” for a 40th anniversary edition. As always the remix is super faithful to the original, but with much improved sonic clarity (something that just can’t be achieved with remastering).
Also remixed for inclusion were many other studio tracks from the 1970-71 period (several previously unreleased), and a 5.1 mix. It should be out on EMI in September.
