Animal Collective have shared "Michael, Remember", a 23-minute improvised jam taken from a May practice, the band's first in a year and a half. The audio is attached to underwater footage filmed at the Flower Garden Banks National Marine Sanctuary in the Gulf of Mexico. Watch it below. "Turn off the lights and watch on as big a screen as possible," the band wrote on Instagram.

Panda Bear, Avey Tare, and Geologist recorded "Michael, Remember" at Drop of Sun Studios in Asheville, North Carolina. (Deakin wasn't present.) The band wrote and rehearsed their new album at Drop of Sun, as previously reported.

The footage was filmed by marine biologist Colin Foord of Coral Morphologic, a collaboration between Foord and musician Jared McKay that explores "the visionary potential of living coral reef organisms via film, multi-media, and site-specific artworks," according to a Vimeo description posted by the band. It was shot in July 2014, and edited together with the audio this month by McKay. Geologist and Deakin assisted with the camera work and the lighting.

The band's last album was 2012's Centipede Hz. Since the release of Centipede Hz, Animal Collective have toured both as a band and as DJs. Panda Bear and Avey Tare also released solo albums.

Earlier today, Panda Bear released "Swallow at the Hollow", a 26-minute mix of unused material recorded around the same time as this year's Panda Bear Meets the Grim Reaper.
