You might not have heard this song but it will be familiar to you because Roger Troutman and Zapp are all over West Coast Rap. Either as an an influence, or a sample or on it. I remember discovering them via an i-D magazine compilation, found in a remainder record shop in Derby.
They weren't exactly obscure but I'd never heard anything like it. It was odd and tight at the same time.
I also remember this appearance on Solid Soul. This is what making an effort looks like.
