Pitch Battle returns to BBC One this Saturday night with its fifth and final heat - but who are the contestants?
Last week saw Portsmouth University Gospel Choir win the fourth heat of the new singing show, securing their place in the grand live final alongside All The King's Men, Scot Soul and Leeds Contemporary Singers.
But who will join them there? In the fourth heat of Pitch Battle tonight, hosted by Mel Giedroyc, six new choirs and vocal groups of all different sizes and musical genres battle it out for the next place in the final.
Tonight’s six groups include a young chamber choir Tring Park 16, a group of musical theatre enthusiasts from the West Midlands Crescendo, an a cappella group from Oxford University Oxford Alternotives and a classical quintet Vox-Xover.
Joining them are all-female pop group Vocalities and all-male barbershop chorus from Dublin, The Ramparts.
Just like last week, to progress our groups must impress the panel of musical judges - the nation’s favourite choirmaster Gareth Malone, former choirgirl turned international recording artist Kelis and a special superstar guest judge - this week it's international popstar Joe Jonas.
The programme opens with an epic musical mash-up, arranged by the Series Musical Director Deke Sharon, who is the Musical Director on the Pitch Perfect movies.
Then groups then go head to head in a series of knock-out choral challenges. First they will each perform their showstopper before battling it out with their opponent in a themed riff-off. The judges will then decide which group goes through to the Solo Battles.
At the end of the programme only two groups will remain where they must face the ultimate sing-off - the Final Battle. Here they share the same song, before superstar guest judge Joe joins in with the group the judges have chosen to go through to the Final.
Joe will return in the live Grand Final to sing with the show’s winning group who will be one step closer to the £50,000 cash prize.
Pitch Battle airs from 7:30PM tonight on BBC One.
