They are now poised to release their fifth studio album entitled Eton Alive on the 22nd February 2019.
The album, which features twelve new tracks from the prolific artists, was recorded in Nottingham.
Jason said: "Eton Alive speaks for itself really. Here we are once again in the middle of another elitist plan being digested slowly as we wait to be turned into faeces once more.
"Some already are, some are dead and the rest of us erode in the belly of prehistoric ideology which depending on our abilities and willingness, assigns to each of us varying levels of comfort that range from horrible to reasonably acceptable, based on contribution.
"So after the digestive system of the Nobles rejects our inedible bones we exit the Arse of Rule, we fall into the toilet again and at the mercy of whatever policies are holding order in the shit pipe of this tatty civilisation.
"It is here our flesh regenerates as we rattle into another form, ready, and ripe for order."
The record will be the first release on Jason and Andrew"s newly formed label Extreme Eating and their first album since parting ways with Rough Trade Records.
Sleaford Mods began when Williamson's friend suggested that he combine his vocals with a music sample from a Roni Size album.
Originally the project was called That's Shit, Try Harder, later changed in reference to Sleaford, a town in Lincolnshire not far from Williamson's home town of Grantham.
But Mods they ain't:
"It was taken over by the terrace mentality quite early on. I think for me it was just snippets of stuff that got through – Weller on The Old Grey Whistle Test when All Mod Cons had just come out, the look of the clothes.
"I didn't really get too deep into it at the time myself. I did a bit more reading later. Then when fucking Britpop came around, some of those ideas came back, supposedly.
"'Clean living under difficult circumstances'... but people just used to use that as a soundbite, didn't they?"
Sleaford Mods new album "Eton Alive" is released on the 22nd February 2019. The band play Bexhill De La Warr Pavilion on Saturday 20th April 2019. For tickets CLICK HERE.
