The end of the series it spans the final ten years (so far) of "Kool & The Gang".
I have never yet been disappointed by a "Kool & The Gang" record and that includes this period that most critics consider a disaster - but I'm not a critic, I'm a fan.
I have both albums from this period ("Unite" and "State Of Affairs") and while they are not what I listen to most frequently, I am certainly glad I have heard them.
I am not going to tell you a track by track opinion of them because my only real complaint against the band is that intro to the first album and even that is nothing major.
So far I have enjoyed to a high degree every "Kool & The Gang track I've heard so if this was released I would certainly not hesitate to get it when I could.
