Carbon Glacier was originally released on CD in 2004, later released on vinyl in 2007. It has been out of print since 2010. It is widely seen as a groundbreaking album in the Laura Veirs canon.

'With her landmark fourth album, Veirs evoked the Pacific Northwest in climactic imagery' - Uncut

"Carbon Glacier is a cold, beautiful and engaging record that translates the bleak, isolated vastness of nature into the bleak, isolated vastness of the modern city-sprawl, leaving one voice to sing in solitude.' - Pitchfork

"This is an oddly beautiful album - far more engaging than you'd expect of one written in a grey Seattle winter, pondering mortality, Moby Dick and the great sheet of blackened ice after which it's named.' - The Guardian

Producer/drummer Tucker Martine (Modest Mouse). Martine allows the experimentation to bloom in all the right places, resulting in a record that never overworks itself, despite being packed to the gills with ghostly glockenspiels, organs, random percussion, and trombone. Veirs' hypnotic voice cuts through it all with deadpan sincerity -- she's equally capable of pitch- perfect beauty ("Lonely Angel Dust") or tightrope uneasiness ("Icebound Stream") -- that comes off somewhere between Nina Nastasia and Jolie Holland.' - All Music Guide
