The sole member of El Perro del Mar, Sarah Assbring (born 1977[1]), initially started as an MP3/CD-R artist and released her first songs through Hybris Records.

Her music could originally have been described as melancholic indie pop, but in recent years she is noted for being a "chameleon" with "every visual, sound, costume, and so on painstakenly thought out" for consecutive albums.

In early 2007, El Perro del Mar ended the relationship with Hybris and started recording for The Concretes's label, Licking Fingers.

[3] In 2015, a deluxe edition of El Perro del Mar's debut album was released, with the package containing eleven bonus tracks including the unreleased demos "In the Woods" and "An Eye for Gold".

On October 10, 2023, City Slang label announced El Perro del Mar signing and a new album Big Anonymous [5] to be released on February 16, 2024.
