The Starsailor frontman has teamed up with Sacha Skarbek to release Lullaby in the UK on September 17.
The collection was inspired by forthcoming film Lullaby, which is based on the Chuck Palahniuk-penned novel of the same name.
Working from a list of song titles, visual references and notes provided by the film's director, Walsh and Skarbek wrote the tracks and recorded them at Abbey Road studios.
Lead single 'Start Again' is available to download now and is inspired by the relationship between Lullaby characters Mona and Oyster.
The characters are played by Natalie Press and Walsh respectively in the accompanying music video.
