Forgotten Kingdom is Causley's first album of entirely self-written material although does include references to traditional song throughout.

Production of the album was then completed by Show of Hands regular producer Mark Tucker at The Green Room studios in East Devon.

Forgotten Kingdom is Causley's most ambitious solo recording project to date and has the largest line-up of guest musicians of any of his albums.

Not all of the songs on Forgotten Kingdom have a traditional folk feel to them and several hint at Causley's songwriting having more modern and expansive influences.

Writing in fRoots, Colin Irwin confirmed his previously stated opinion that Causley is "the finest singer of his generation".
