Earth, Wind and Fire, Leonid and Friends - September (LaRCS, by DcsabaS, 2018)

"LaRCS" stands for "Live and Record Combined Stereo", which means that on the left side you can hear a live performance, while on the right side the video clip/studio version.
In this case you can enjoy "September" from the Earth Wind and Fire: on the right side the official music video clip, while on the left side a great live cover version from Leonid and Friends (2018, tempo adjusted).
