I go retro.... 70s & 80s scene Music CD cover

I was given another opportunity to design an album cover (from Life Records), a compilation album of the 70s / 80s music scene in Singapore. Growing up loving songs from the retro era, I don't have much problem coming up with the concept, but as far as possible, I want to have it looking fresh with a simple touch of retro.

The one on the left is the original artwork before the touch up.
The one on the right was given a slight color treatment.
