Grouper is the solo project of musician and artist Liz Harris. After releasing material independently beginning in 2005, Harris released the critically acclaimed Dragging a Dead Deer Up a Hill (2008), followed by four more records, including a two-part concept album, A I A. Her tenth studio album, Ruins, is due for release on October 31, 2014.

Harris' music, described as "ethereal" and "hazy," often consists of guitar layered with vocals and tape loops. She has collaborated with a number of other artists, including Xiu Xiu, Lawrence English, and Jefre Cantu-Ledesma. In 2012, Harris collaborated with Cantu-Ledesma on a seven hour long music performance titled Circular Veil, designed to mimic a full sleep cycle. She resides on the Oregon coast.
