Kanye West and Spike Jonze first teamed up a few years ago for the luridly violent video for “Flashing Lights.†Apparently the collaboration went well, because the two ended up working together on a new short film called We Were Once a Fairytale, featuring Kanye’s song “See You in My Nightmares.†The project, which debuted in June at the L.A. Film Festival, will arrive on iTunes on September 8. However, just in case you think the two have gone soft, the video is said to feature rose petals vomiting, West engaging in knife play, and a demon rodent emerging from his stomach. [We Love You So]
