Chic - Le Freak (LaRCS, by DcsabaS, 1996 Budokan ft Slash, 1979)

"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 "Le Freak" from the Chic. On the right side you can see a TV show performance from 1979, that was playback, I suppose (edited and tempo adjusted), while on the left side a live performance from 1996 (Budokan, Japan, frequency and tempo adjusted) featuring Slash on the solo guitar.
