The Oh Hellos began in a cluttered bedroom, where siblings Maggie and Tyler Heath (born and raised in southern Texas) recorded their self-titled EP in 2011. In the fall of 2012, the sibling duo released their debut full-length record Through the Deep, Dark Valley, an album full of regret and redemption, which they wrote, recorded, produced, mixed, and mastered themselves.

When the time came in early 2013 to bring the music to the stage, the Heaths reached out to friends both new and old and gathered together an ensemble of touring musicians the size of a circus, tumblers and all.

Their second full-length album, Dear Wormwood, is a collection of songs inspired in part by C.S. Lewis' The Screwtape Letters and Patrick Rothfuss' The Name of the Wind, mythology and folklore, and apocalyptic literature. The album tells the story of a protagonist trapped in an abusive relationship, by way of letters written to the antagonist. It was recorded, piece by piece, in the house where Maggie and Tyler live in San Marcos, TX, and much like The Oh Hellos' live performance, the album presents two alternating faces: at times delicate, intimate, affectionate; and at others, soaring and towering and joyfully explosive.

Their influences range from Fleet Foxes and Sufjan Stevens to The Middle East and the Muppets, bending and blending styles and genres into a unique mixture of eclectic folk rock.
