The duo are currently working on their third album, the follow up to last year's Now This I Have To Hear, and are looking to fans to help decide on the accompanying artwork.
In a post on their MySpace, the band say "Now that this third album is developing nicely on the music front we want to get ahead of ourselves and get on top of the artwork before it becomes a mad scramble."
Fans should be on the lookout for "interesting images, pieces, graphics etc" for the act to use on their new LP. All you creative types, you can get in touch via their website.
And if you need a little musical inspiration, Messiah J & The Expert play a December 14 support slot for the Delorentos in Dublin's Ambassador Theatre.
