What a big mess. I could see that the Whitesnake (1977), Northwinds and Into the Light albums were in there, but what is all the other stuff in there? So this is the breakdown from Rhino's site.

Disc One
Into the Light (Remix)

Disc Two
Tracks 1-5 = Into the Light (Additional Remixes)
Tracks 6-17 = Demos and Unfinished Symphonies (David Coverdale with Tony Franklin)
Tracks 18-20 = Original David Coverdale Demos from 1997 with Tony Franklin

Disc Three
Northwinds (2024 Remix)

Disc Four
Tracks 1-9 = Whitesnake 1977 (2024 Remix)
Tracks 10-17 = David Coverdale 1968 Home Demos (that's what it says - 1968 - Coverdale would have been 17 years old at that time)

Disc Five
Into the Light (Original Mix Remastered)

Disc Six
Tracks 1-9 = Whitesnake 1977 (Original Mix Remastered)
Tracks 10-17 = Northwinds (Original Mix Remastered)
