Clean Bandit and Zara Larsson performed on The Voice UK live shows this week.
The acts were the first guest stars to be announced for this year's finals, performing on Saturday night's show.
They took to the stage with their new collaboration Symphony which is out this week.
The stunning performance proved a hit with viewers, as they voted in the quarter finals.
Unlike The X Factor or Strictly, The Voice UK aired its results on the same night as the performances.
In fact, this year there isn't even a separate results show with just the one episode each weekend.
Last night on The Voice UK the 12 remaining singers performed for a place in next weekend's semi-final.
Members of Team Gavin, Team JHud, Team Will and Team Tom all sang to stay in the competition and be one step closer to winning a recording contract with Polydor Records.
The pressure was on with four acts going home.
Each coach first got to save one member of their team: Will.i.am saved Jason Jones, Tom saved Into the Ark, Gavin backed Truly Ford and finally Jennifer's gave her fast pass to Mo Adeniran.
The rest of the contestants then faced a viewer vote and in the live results host Emma Willis revealed that Craig Ward, Max Vickers, Jamie Miller and Michelle John had been SAVED by the public.
That meant that Jack Bruley, Sarah Morgan, Tanya Lacey and Nadine McGhee were sent home, as it happens one act from each of the four teams.
The Voice UK returns next Saturday night live on ITV.
