Animal Collective is an American experimental pop band formed in Baltimore, Maryland in 2003. Its members and founders are Avey Tare (David Portner), Panda Bear (Noah Lennox), Deakin (Josh Dibb), and Geologist (Brian Weitz). The band's music is characterized by studio experimentation, vocal harmonies, and an exploration of various genres which include freak folk, noise rock, ambient drone, and psychedelia. Records released under the name "Animal Collective" may include contributions from any or all of its members. In the case of Dibb, who often takes breaks from recording and performing with the band, his time off does not constitute full leave.
The band members met in school and started recording together in various forms of collaboration from a young age. Evolving from collaborations between Lennox and Portner, the collective was not officially established until all four members came together for the album Here Comes the Indian (2003). Most prior collaborations between the band members were then retroactively classified under Animal Collective's discography. In 1999, they established the record label Paw Tracks, issuing what is now considered their debut album, Spirit They're Gone, Spirit They've Vanished (2000), as well as work by other artists. In 2009, the band released their most commercially successful album, Merriweather Post Pavilion. Its rich, reverb-heavy sound proved influential to much subsequent popular music.
