Synopsis

Cassius' "I Love U So" turns a simple lyric into an interactive lip-sync experiment. Eight different mouths perform the song's repeated vocal line, appearing one after another and combining in tightly edited visual patterns. Built around an iPhone application, the video lets viewers select mouths, rearrange them, and create their own versions of the performance. The result is playful, hypnotic, and deliberately minimal, with the shifting lips becoming the sole visual focus.

Factoids & Trivia

• The video was released in 2011 alongside an iPhone app that allowed viewers to remix the mouth performances and make personalized versions of the clip.

• Its concept was designed as more than a finished music video: it also functioned as a demonstration of the app and encouraged fans to submit their own creations.

• Eight separate mouths were used for the performance. The deliberately limited lyric - "I love you so / But why I loved you, I'll never know" - made the visual repetition especially effective.

• The clip appeared during a period when smartphone-based interactive music videos were still relatively unusual, helping it attract attention beyond the electronic music audience.

• The track later gained additional exposure when Jay-Z and Kanye West heavily sampled it for "Why I Love You" on their 2011 album "Watch the Throne".

• The video includes appearances from figures associated with the French electronic scene, including Cassius member Philippe Zdar and Ed Banger founder Pedro Winter.
