Musicians Marlon Williams and Delaney Davidson will return to Masterton thanks to popular demand.
The pair performed as part of the concert A Night at the Museum at Aratoi earlier this year. And Mark Rogers, of organisers Up With People, said the show had gone "down a storm".
He said audience members had posted pleas on Facebook to bring the pair back.
"Their last concert in August was a huge hit and Katie Grantham and I have been inundated with requests to get them back, so we are delighted that they'll be here."
The pair will be promoting their new album Sad But True, a collection of covers and originals.
