"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 "Money for Nothing" from the Dire Straits. On the right side you can see the official music video clip (edited), while on the left side a live concert version from 1990 (Knebworth, tempo adjusted). Eric Clapton joined Mark Knopfler on the stage.
