This is a masterpiece performance by Earth, Wind & Fire back in 1981.
This was played in Oakland. I recommend this groove to everyone, which I have this very concert on CD which is as rare footage as you can can in all of EWF history!
Just observe the whole band, Andrew Woolfolk shakin' away and Larry Dunn just enjoying the music. The whole gang at the end, just having a laugh at what is considered to be the one of their grooviest concerts EVER!
Enjoy!
