Kerry Dylan McCoy[3] (born January 26, 1988) is an American musician, best known as the guitarist of San Francisco–based blackgaze band Deafheaven.

McCoy is a native of Yuma, Arizona, and lived in Port Hueneme, Oxnard, and Stockton, California, before moving to Modesto at age 10.

The duo recorded an untitled demo album in April 2010 at Atomic Garden Studios[9] with Jack Shirley for about US$500, which they could not afford at the time.

[10] In 2010, Deafheaven became a five-piece with the addition of bassist Derek Prine, guitarist Nick Bassett and drummer Trevor Deschryver.

[5][12] McCoy's guitar playing incorporates influences from various genres atypical of traditional black metal sound, including shoegaze, dream pop, post-rock and indie rock.
