Justin Finch of Fanfarlo has a solo project called The Castle which he explained on the band's website:

Maybe it was the excitement of writing and recording the new Fanfarlo record that inspired me to finally try and produce some of the triumphant, science fiction inspired synthesizer sounds battling it out in my head. I've decided I don't want to be too precious about it so I'm putting it online in it's semi-finished state. Presenting The Castle.
