A couple of years ago, Animal Collective took over the Guggenheim to perform a one-off art/music project in weird costumes called Tranverse Temporal Gyrus. The group is just now getting around to putting out a recording of the music with a limited-edition vinyl for Record Store Day:
For the audio, each member of the band made individual sounds and songs. Over the course of two, three-hour performances, the basic tracks were fed into a computer program that randomized the track order, and sometimes randomly combined stems from one track with stems from another. The program also panned the music in various directions around a 36 channel surround sound system that ran through 36 speakers set up from the top of the Guggenheim's l ramp to the bottom. The music on this 12" is a collage we made consisting of the original tracks, as well as live recordings made inside the Guggenheim before the doors were opened to the public. It will be the only physical format on which any of the music will be released.
It looks like the vinyl itself is all sold out, and if any of that was too complicated anyway, there's also an easy YouTube stream available below. Also, check out a special online portal that Animal Collective built to experience the album visually, as well.
