I think this album is worth a listen. It takes courage, EGO (in the largest sense), and maybe a little Brain Damage to make an album like this. I think he even acknowledges this in the first few moments of Brain Damage. Hense Redux added.
Whenever I listen to my favorite version of Echoes (from original Live at Pompeii), I hear something different, and yet I always hear the same thing: 4 people playing together. Really playing together, each contributing an essential part. I try to listen to each member separately. When done, I am left with the thought the results are greater than the sum of all parts.
That base is what helped make the original Dark Side album so successful ... and ... great.
And that history is why this album deserves a listen to. It is an interpretation from one part, 50 years later. While it may sound like the idea came from "What if we only record my (updated) parts?", there are only three people left in the world who have the right to say and do that. Here is one of them.
Comparing this album to the original is pointless but listening to this album after knowing the original, as well as the off-stage history, is worth 47 minutes.
