The 15th annual Mobo awards are due to be held, featuring a host of international stars.
The "music of black origin" ceremony will be held at Liverpool's Echo Arena and presented by Strictly Come Dancing's Alesha Dixon and Radio 1 presenter Reggie Yates.
The show will close with a performance from Tinchy Stryder, who will be joined on stage by the year's leading Mobo nominee Tinie Tempah, as well as Professor Green, Devlin and Giggs - the cream of the UK hip hop and grime scene.
JLS also have a world exclusive collaboration up their sleeves with a surprise US star, organisers said.
Tinie Tempah, NDubz, JLS, Professor Green, Jay Sean, Mark Ronson and The Business INTL, Roll Deep, and Nelly are already confirmed to perform live.
Guest presenters on the night will include last year's backstage host, Peter Andre, The Saturdays' Rochelle Wiseman, JLS and Destiny's Child star Michelle Williams.
