i looked around and haven't been able to find those fonts

I also suggest looking at all of the old Clinton, P-Funk, Parliament, and Funkadelic album art for some inspiration.
Some of the covers were very cool and some were terrible.
Just see what appeals to you and try to bring it all together.
That's one nice thing about working in layers. It makes it easier to change things and experiment with different ideas without having to redo everything
