Blackout Artist
An artist who blacks out when making work - from the process, not alcohol or drugs. A counterpoint to a meticulous or methodical artist, this person creates her best work in the rush of the moment and rarely remembers the process.
When the blackout artist came to she looked at her canvas and didn't remember her painting, but liked it.
