Esthero is a Canadian singer-songwriter who lives in Los Angeles, California. The name Esthero refers both to the singer and formerly to the two-person team of herself and producer Doc McKinney. Esthero is a portmanteau of "Esther the hero"; she claims to have gotten the name by combining the name of the heroine (Esther) and last line of the film from Sylvia Plath's novel The Bell Jar.
