Los Angeles music scene and caught the eye of many record labels. He said at the time it did not feel right because labels were trying to conform him into a certain image and he was still trying to discover the artist that he wanted to be. He decided to turn down these labels and move to
Asheville, North Carolina. His resistance to labels is reflected in his later album,
Græ. Sumney joined
Terrible Records after the release. He considers his songs to be performance based, and that many of his recorded compositions derive from fleshing the songs out through live performance. He has performed at venues such as the
