Horn of Plenty was originally released in November 2004, and then re-released with a bonus CD of remixes one year later. There have been 3 different, limited pressings of Horn of Plenty on vinyl, most recently for RSD 2013.
This is our original description from 2004:
Horn of Plenty is a nostalgic amalgamation of found sounds and layered vocals bound to thrill followers of Animal Collective, Sufjan Stevens, Nick Drake and the Unicorns. While the album pushes the boundaries of mellow into undiscovered territory, Grizzly Bear is not sure if they fall under the newly coined “freak-folk” category or the new-folk genre, but they’d like to offer up wood-temp or cave-core. V Magazine likened them to Neil Young on cough syrup.
