Simply put, this is the musical journey James Brown took as he developed Funk as a genre. Yes, others were working in the same direction, and they all have a place, but listen here and you will see the Foundations of Funk - the title is, in this case, exactly what you get.
From the early instrumental workouts, it is possible to see how JB arrived at "Cold Sweat", with its "on the one" opening. In all it's 7+ minute glory, you also get to hear the way a track developed under JBs direction - "give the drummer some" for example, and this track is not unique in that.
This set takes you up to the point where the original band members were replaced, by, among others, Bootsie Collins and his brother, so there is no "Sex Machine", for example. You do get "Say It Loud.." as well as "Funk Drummer", the track that has been sampled on innumerable Rap and Hip Hop tracks.
For the more casual listener there are a huge variety of compilations which will probably fit the bill better(try "In The Jungle Groove" for example), but this is recommended for completists and enthusiasts, who will also love the detail brought out of the archives by the CD booklet - you get to see who played what on every track !!!
