A press release can now be found over at Elsewhere complete with track listings for the three CD’s that this anniversary edition consists off.

All three of the cd’s have 12 tracks.
The first CD is the “old” release of Vangelis Blade Runner Soundtrack.
The second CD consists of previously unreleased + bonus material.
The third and final disc will be of real interest to Vangelis fans – as it contains an entire album of newly written material composed by Vangelis to mark the 25th anniversary of Blade Runner. The music is strong and flowing, and retains the dark, atmospheric sense of the original score. There are some intriguing spoken word contributions too, from Ridley Scott, Roman Polanski, Oliver Stone and a host of distinguished actors, personalities and world dignitaries.
