The additional night will be headlined by Manchester band James, supported by the Lightning Seeds and Get Cape. Wear Cape. Fly.
It will take place in the stunning 54-acre grounds of Williamson Park on Thursday, September 2.
Festival favourites James will take to the stage to play classics from their back catalogue, plus brand new music including their new single "Beautiful Beaches" from their latest studio album All The Colours Of You.
The new album from James is set to be released on June 4.
Since releasing "Sit Down", their breakthrough single in 1991, James has released a grand total of fifteen studio albums, selling over 25 million copies in the process.
The band continues to perform countless headline shows and festivals across the world, with a UK arena tour scheduled this winter.
Liverpudlian rock band Lightning Seeds have already been confirmed as a support act for the gig.
The legendary band will light up Lancashire on Thursday night, playing the music that made them famous over their long career, such as hit tracks including "The Life of Riley", "Pure", and "Lucky You".
Get Cape. Wear Cape. Fly will also delight gig-goers as the English musician, also known as Sam Duckworth, joins the two bands at the gig on what will be fifteen years since the release of his debut album The Chronicles Of A Bohemian Teenager.
Highest Point Festival, which was originally set to take place in May 2020, will now span three nights from September 2 to September 4 with a bigger capacity and brand new stage.
The full line up for the event was announced earlier this month and boasts a plethora of acts, with headliners to include Rag’N’Bone Man, Rudimental, Clean Bandit, Becky Hill, Hybrid Minds and The Futureheads.
