Jubilee Square, off High Street, will welcome the Luminites, who count Simon Cowell as a fan, and The Voice favourite Joseph Apostol.
The acts are in the line-up for MidKent College’s tour of Kent.
Soloist Apostol, from Gillingham, who was a student at the Medway campus, has appeared at all five shows, including Fremlin Walk on Monday, but the Luminites will only appear for today’s performance.
It will be the second time the foursome, made up of Steph Edwards, Ben Francis, Jordan Clark and Corey Layzell, have visited the town. They dazzled audiences at last year’s roadshow before they soared to fame on Britain’s Got Talent.
Music guru Cowell, and fellow judges David Walliams, Amanda Holden and Alesha Dixon, praised the band for their natural talent and were left impressed with their song-writing skills.
The famous panel’s predictions for the group’s bright future came true last week when the singers signed for Sony Music Entertainment.
The friends, who started out as buskers, celebrated their record deal with an overnight stay at the De Vere Village Hotel, off Forstal Road, Sandling, on Wednesday.
Both the Luminites and Apostol made it through to the semi-finals of their respective shows. They will be joined by various other acts on today’s stage, including former X Factor contestant Mike Hough, who appeared on the ITV production in 2009.
The roadshow, which is hosted by kmfm presenters, will run between 11am and 2pm.
