Jersey Live festival organisers have confirmed The Rapture, King Charles and Craig Charles for the annual event.
The Rapture, a dance-punk band from New York will perform on Sunday, supporting headliner Plan B.
The band, who's biggest hit was "House of Jealous Lovers", will be releasing their new album just after the festival on 5 September.
Organisers also confirmed indie-folk singer King Charles and BBC 6music DJ Craig Charles who will perform in the hospitality stage.
Festival director, Warren Le Sueur, said: "Adding The Rapture, Craig Charles and King Charles to the already stellar line-up is making JL 2011 stronger and better than ever.
"Tickets are selling very well online, and with [Jersey Telecom's] mid-June promotions due to be released, we are looking forward to hopefully another sell out event as per last year."
London based singer-songwriter King Charles has been tipped as a great act by BBC Introducing's Huw Stephens and Tom Robinson for his "quintessentially English folk".
He will perform twice on Saturday, on the new SoBe stage and on the Hospitality stage.
BBC 6music DJ Craig Charles will make a return to the Jersey Live stage, this time hosting the Hospitality stage as well as DJing.
Charles, who presents the Funk and Soul Show for BBC 6music, hosted the main stage at Jersey Live in 2009.
He will join a host of BBC Radio DJs at the Royal Jersey Showground in Trinity for the Jersey Live weekend.
Huw Stephens will host the main stage and Zane Lowe from BBC Radio 1 will headline the Dance Arena.
Lowe's fellow BBC Radio 1 DJ's Annie Mac and Toddla T will be in the Dance Arena.
The event will be headlined by Madness on Saturday with support from The Streets, while on Sunday Plan B will take the top slot.
BBC Jersey will be at the festival throughout the weekend.
BBC Radio Jersey will be broadcasting live on Saturday as well as playing interviews with the biggest names the following week.
There will be full highlights on BBC Channel Island News on Monday on BBC One.
