Big Blood is an American psychedelic folk band formed in South Portland, Maine, in 2006 by Colleen Kinsella and Caleb Mulkerin. The duo had previously been part of Cerberus Shoal but left to focus on raising their daughter Quinnisa Rose Kinsella Mulkerin. Big Blood's early albums included Strange Maine 11.04.06 (2006) and Sew Your Wild Days Tour Vol. 1 (2007), which were self-released through their DIY label Don't Trust the Ruin. Their approach to packaging, featuring handmade artwork and ephemera, gained attention in the underground music scene. In 2010, they released Dead Songs (2010) and began distributing albums through independent record labels. Notable collaborations include the album Big Blood & the Bleedin' Hearts (2008). Their work received positive reviews from outlets like The Boston Phoenix and WFMU.
