Davis, who also presents a show on a radio station in Essex, will perform in the Stonebridge Bar.
He said, “There’s novelty value of some boring snooker player suddenly playing electronic music. I’ve got my wellies ready and we’re going to go down there and bring our records.”
In the 1980s, Steve Davis won the World Championship six times and was ranked world number one for seven consecutive seasons.
It has not yet been confirmed which day of the festival Davis will appear on.
Asked about the genre of music he will be playing, Davis said, “It’s not necessarily techno. We’re playing some stuff that’s electronic and some that will appeal that people who are into IDM [intelligent dance music].”
“Stuff that’s a bit more complicated and a little bit more leftfield than ‘doof, doof, doof’.”
“It’s more about trying to introduce some artists that you may not know exist, who are in a like-minded vein. On the radio show, we get a good soundboard for what might go down well.
“Obviously, when you’ve got to have your foot tapping, you’re limited to what you can play. You can’t put any stroky beard stuff out there.”
Davis started playing dance music on his local commercial radio station, but has since moved on to festivals and gigs.
He added, “It’s quite strange. I’ve been doing a radio show in Brentwood, and I’ve joined forces with a musician, Kavus Torabi, who’s been in a few bands over the years. We’ve got quite a mini following online, it’s a little bit culty.”
This year’s Glastonbury festival begins on 22 June on Worthy Farm, Somerset.
