efLe Bon's first official release was a Welsh language EP, Edrych yn Llygaid Ceffyl Benthyg ("Looking in the Eyes of a Borrowed Horse", similar to the English expression "to look a gift horse in the mouth"), on Peski Records in 2008.[1] She also self-released the double A-side debut single "No One Can Drag Me Down / Disappear" (described by Gruff Rhys as “Bobbie Gentry and Nico fight over a Casio keyboard; melody wins!”) on her website. Le Bon worked alongside Gorky's Zygotic Mynci's Megan Childs, who contributed violin, and Super Furry Animals and Thrills collaborator John Thomas, who added pedal steel.[2]
Her debut album, Me Oh My (previously known by the working title Pet Deaths), was released in 2009.
In 2010, Le Bon provided backing vocals on several tracks from The Gentle Good's second album, Tethered for the Storm.
In 2011, Lex Records artist Boom Bip featured Cate's voice on the track "Do as I Do" on their Zig Zaj release.
In 2012, Le Bon released the album Cyrk, followed by the Cyrk II EP.
In January 2013, Le Bon moved to Los Angeles to further her career in the US.[3] Her next album is being produced by Noah Georgeson and Josiah Steinbrick in Los Angeles and features H. Hawkline on guitar.
