Is it funk or hip hop... because funk is the 70's and hip hop is 80's and later. Two totally different music genres. Funk is a blend of rock, soul, and blues.
Hip Hop is a blend of disco and rap. If it is funk, look for something by Funkadelic, Parliament, The Average White Band.... Perhaps... AWB - This World has Music? The above are all 70's ... funk.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
