Grouper is the solo project of musician and artist Liz Harris, of Oregon.
Harris’ first album was 2005’s Grouper, a self-released full-length CD-R, followed later that year by Way Their Crept on Free Porcupine (re-released in 2007 on Type Records). Other recordings include 2006's He Knows, released as a 3" CD, the 12" Weird Forest release Wide in 2007, and a 7" called Tried.
She released a collaboration album with Xiu Xiu in 2006, entitled Creepshow.
Harris released her third full-length album, Dragging a Dead Deer Up a Hill, in 2008.
Early in 2012, Grouper performed Violet Replacement in the UK and Europe, a pair of longform tape collage pieces which originally took shape for commissioned performances in New York and Berkeley.
At Berlin's Club Transmediale festival in early February of 2012 Harris premiered a new work called Circular Veil in collaboration with Jefre Cantu-Ledesma--seven hours of music, designed to mimic one full sleep cycle.
