"LaRCS" stands for "Live and Record Combined Stereo", which means that on the left you can hear a live performance, while on the right the album or clip version.
Regarding the current video, you can enjoy "HeartBeat Rock" from Kylie Minogue: on the right side after the intro you can hear the album version together with the screen projection as a kind of video clip, while on the left side a live concert version from 2008 (X2008 tour, London). Links:
