Lester Bowie spent 6 months in Lagos with Fela Kuti in 1977.
Here’s an interview where he tells the full story

Basically, I always believed art is functional. It’s not just something you put in museums, it’s better for it to be used for something functional: educational usage, therapeutic usage. But it should be USED. Music should be used, not just as entertainment. I’m not saying it’s NOT entertainment. It’s EVERYTHING. It’s entertainment, it’s religion, it’s a lot of things. That’s what most of what our conversations would be about: the spiritual aspect to the music, what binds all these different types of musics together.
