The stereo mix and mastering of all these tracks are fantastic! This is one of the better remastered CD's out there if you're like me, and suddenly get the urge to own about ten best of packages of artists from the British Invasion.  Though The Beatles truly represent the start of the British Invasion, you know the song "House of The Rising Sun" is probably the most important song ever of the British Invasion.  The Animals have had many best of collections released over the years.  But this collection called "Retrospective" is the closest you're going to get to a complete collection on one CD.  The only disappointment I have is that it has the shorter 45 version of "Spill The Wine" which is basically Eric Burden and War.  But, I have the full version available to me on one of my many various artists collections.
