An experimental band led by Seattle musicians Faith Coloccia and Aaron Turner, Mamiffer intertwines elements of ambient, drone, and post-rock composition with ethereal vocals. The project grew out Coloccia's work wither her former band, Everlovely Lightningheart, and featured a rotating cast of collaborators with Turner, formerly of the band Isis, eventually becoming her primary creative partner and later, her husband. Since the late 2000s, Mamiffer has released numerous albums, EPs, split releases, and collaborations including 2013's acclaimed Bless Them That Curse You, 2015's Crater, and the dreamy 2019 LP Brilliant Tabernacle.

Following the breakup of Everlovely Lightningheart, Coloccia spun some of her unused ideas into a new project intended to include an ongoing rotation of collaborators. A 2007 recording of Coloccia and a couple of friends playing manipulated tape loops live in an abandoned tunnel called the Hell Hole in Desert Hot Springs, California constituted Mamiffer's first release, though it was 2008's studio album, Hirror Enniffer, that stood as their formal debut. By this point, Turner had already become a primary member and released the album on his own Hydra Head label. Three years later, Mare Decendrii marked the band's first release on SIGE Records, a label Coloccia and Turner had recently launched to encompass their various experimental releases, including splits with House of Low Culture and Pyramids. Mamiffer's first collaborative album, Bless Them That Curse You, appeared in 2012 and saw them teaming up with Chicago drone act Locrian to rave reviews. For their own third solo album, Mamiffer strove for a more minimalist and repetitive tone, and recorded 2014's Statu Nascendi without drums. Curiously, the album was partly funded by earnings from fashion design house Prada, which had used one of their songs in a commercial featuring actor Ethan Hawke. 2015's Crater was another collaborative release, this time with Portland artist Daniel Menche. Returning the next year, Mamiffer's The World Unseen had a reflective tone with Coloccia's vocals mixed more into the forefront. Following a 2017 compilation of samples called Recordings for Lilac III, the band returned in 2019 with the deeply ethereal and contemplative Brilliant Tabernacle. ~ Timothy Monger, Rovi
