Liverpool has had a huge influence on music, producing acts including The Beatles, The Wombats, The Zutons and Atomic Kitten.
Sefton Park is located in south Liverpool, about a 20-minute drive from football stadium Anfield.
The team are scheduled to play the final match of their Premier League season on the Sunday of the festival - and are currently favourites to win the title.
Acts previously announced to be performing during the weekend include Myles Smith, Wet Leg, Blossoms and Lola Young.
Last year, Coldplay, Raye and Chase & Status topped the bill for the event held in Luton.
And previous Big Weekends have seen the likes of Taylor Swift perform in Norwich, Miley Cyrus in Middlesbrough and Ed Sheeran in Coventry.
