R.E.M. is now up to four in its quest to release videos for each song on Collapse Into Now with these three new ones rolled out in the last week. Filmmaker and music video director extraordinaire Lance Bangs took on the the upbeat "Alligator Aviator Autopilot Antimatter" with the help of Peaches and some funky costumes. French conceptual artist Sophie Calle's clip for "Walk It Back" sort of defies description, or maybe is just better left undescribed. Finally, artist and "Nowhere Boy" director Sam Taylor-Wood follows her fiance and "Nowhere Boy" star Aaron Johnson for an incredibly jaunty stroll in the video for "Überlin". You can watch all three below. Keep an eye out for future videos from James Franco and Albert Maysles, and watch Dominic DeJoseph's video for "Mine Smell Like Honey" here.
