Frost took the spotlight in 2007 with his critically acclaimed LP Theory of Machines. Wire Magazine called it "simply awesome—this is Arvo Pärt as arranged by Trent Reznor," and the BBC's Mary Anne Hobbs called it "arresting and exquisite" including the title cut on her acclaimed Evangeline compilation. Taste-making European music retailer Boomkat named Frost "one of the most interesting and groundbreaking producers in the world today" and even went so far as to call Theory of Machines "the future of electronic music."

Three years later, Frost returns with BY THE THROAT. Produced in Iceland by Frost and Valgeir Sigurðsson (Björk, Coco Rosie, Bonnie "Prince" Billy), the album also features performances by Amiina, The Arcade Fire's Jeremy Gara, Swedish metal outfit Crowpath and composer Nico Muhly.

Aside from the traditional musical language of harmony and melody—as with the strings on "Leo Needs A New Pair Of Shoes"—BY THE THROAT includes musique concrète, weaving nonmusical sounds into the sonic fabric. Wolves snarl and lions groan in "Killshot;" the microscopic clicks and whirs of killer whales on the hunt in "Through The Roof Of Your Mouth;" and the unmistakable sound of a human gasping for breath in "Híbakúsja." There is also the sheer physical experience, the visceral effect of Frost's seismic rhythms and high-pitched shrieks on the listener's body.
