Indeed there are. Well three actually.Is there two different versions of this album?
The Bright-Side Mix version is mixed by Mark ‘Spike’ Stent, and the Dark-Side Mix version by Tchad Blake. These are available together as a 2CD set or as individual 2LP vinyl packages.
A 2CD+blu-ray edition features both stereo mixes on CD and a blu-ray with a Dolby Atmos Mix known as the In-Side Mix which was created by Hans-Martin Buff.
I have the 2CD plus Blu-ray version and so far I am favouring the Bright-Side Mix for eight of the tracks and the Dark-Side for the remainder. I haven't heard the Atmos mix at its best yet as don't have my surround system set up right now (house renovation project has seen that go into storage), but will be interested to listen properly when I can.
