A music festival with five stages will take place at Newhaven Fort on Saturday September 27.
Rock and acoustic music, as well as DJs from London, Brighton and the local area will feature.
The Festival of Sound will even include lighting and visual effects, with genres from drum and bass to country rock.
Festival of Sound spokesman Dean Amy said: “It’s a fantastic venue that gives us the opportunity to create very unique stage areas and lighting effects to transform what is already a very impressive structure.
“It will be a mass of colour and amazing effects never before seen at the Fort.”
“The stage areas will consist of, Main Stage, Local Band Stage, Acoustic Stage, Main DJ Stage and Local DJ Stage. As well as the sound and light, the festival will have fully licensed bars and food areas.”
Confirmed acts are The Skarlettos, The Corrupted, Snakebite, Krypton, Markham & Lodge, Badger Attack, The Firm, The Bourbon Cowboys, Random, Crooked Rooks, DJ’S Morf, Risky, Tetris, Secret C, Zodiac & Sequoia, Matthew Matheson, Elusive and Dan Barnes with more to be announced.
Dean added: “We are very lucky to have had huge support from both the Fort and the general public.
“With the production and main stage in the capable hands of Arena entertainments, who have worked all around Europe and who are currently supplying Brighton Pride with their stages and visual effects, I know the Festival of Sound will become one of the must see event in The Fort’s calendar.”
Doors open at 5pm and the event will finish at 11pm with tickets now on sale from the Fort, in Fort Road at £11 each.
