ALL grandparents have a right to brag, but not all can call their grandson a rising musical superstar.
Regency Park residents Brenda and Neville Black will be cheering on their grandson Robbie Balmer once again when he competes on The Voice on Monday night.
"We are absolutely over the moon," Brenda said about her grandson's success on the show so far.
"His family have all been musical. His dad played guitar when he was little, and his sister plays the piano beautifully."
The Brisbane boy watched the last episode in Warwick with his grandparents, and is one of the final 16 contestants in the talent show, heading to London with coach Kylie Minogue.
However, the trip overseas with Team Kylie is only a small part of a long journey for Robbie since he auditioned in September last year.
Before then, the 19-year-old performed at a few pubs and clubs in Brisbane and even made an appearance out the front of the Warwick Town Hall during the Jumpers and Jazz festival.
Originally enrolled in an engineering degree, Robbie moved into music, much to the delight of his grandparents.
"He is very grounded. I could listen to him all day," Brenda said, surprised at how fast word of Robbie's appearance on the show spread.
"People we know have stopped us to say they have seen him on TV," she said.
"Oh, it's just great - the best part is it gives us a bit of interest and something to follow."
"The show means so much more when it's personal," Neville added.
The pair, who had never watched The Voice before this season, said they now haven't missed an episode.
"When it comes to vote, we definitely will be calling in," Neville said.
"We have no idea how he will go from here, but whatever happens, he has made some wonderful friends and it's been a great opportunity."
Catch Robbie's next performance on Channel 9 at 7.30pm on Monday night.
