They will be supported by Velocity Brown and The Hotrods and The Stars Band to promote Tramlines - the UK’s largest inner-city festival, which will unveil its newly-expanded Devonshire Green stage of Friday.
The Devonshire Green stage has an increased capacity for 2016 and can now hold up to 7,500 revellers.
Sheffield favourites, The Everly Pregnant Brothers, were conceived during a drinking session involving artist Pete McKee and ukulele player Richard Bailey.
Velocity Brown and the Hotrods have played at Glastonbury and Shambala.
Completing the bill on Friday night are The Stars Band, a group created at Under The Stars - a music project for people with a range of hidden disabilities.
Tramlines organisers have also today announced those chose to perform at the festival through the Apply To Play scheme.

Barnsley indie-rock outfit Aztec Doll, Manchester afro-beat 11-piece Agbeko and Leeds experimental multi-instrumentalist Juffage will appear across a range of venues and stages including the Main Stage and Devonshire Green.
