A co-project between Smith and German electronic duo Mouse On Mars, Von Sudenfed are set to unleash their first album in May, through Domino Records.
That means fans will have plenty of time to familiarise themselves with their brand of electro, dubstep and disco before they appear at the Garden Party on June 6.
Also newly announced is the Mad Professor, who's perhaps best known for his dub albums, which include 12 installments of the Dub Me Crazy series and five albums under the Black Liberation Dub banner.
