Unknown Mortal Orchestra

Unknown Mortal Orchestra is an American and New Zealand rock band composed of singer, guitarist and songwriter Ruban Nielson, bassist Jake Portrait, keyboardist Quincy McCrary, and drummer Amber Baker. The band was started by Nielson (formerly of The Mint Chicks).
Singer and guitarist Ruban Nielson released the track "Ffunny Ffrends" on his anonymous Bandcamp profile on May 17, 2010. It was paired with no further information and notably no mention of who created it. Within a day, the song had received significant coverage from independent music blogs such as Pitchfork. Through their reposting and attempts to hunt down the creator, Nielson eventually claimed the track as Unknown Mortal Orchestra's. (Wikipedia)
