An award-winning A Cappella group have stunned the audience of BBC2's The Naked Choir with a stunning rendition of Sinead O'Connor's Nothing Compares 2 U. 

The breathtaking vocals from Choral Stimulation on the 1990 hit written by Prince has received praise from the show's presenter Gareth Malone OBE who said their rendition was "guaranteed to give you goosebumps" on Twitter.

Singer Cailtin Sinclair took the lead on the track. 

The Glasgow University vocal group are appearing on the show which follows Malone as he searches for Britain's most entertaining amateur singing group. The contest, however, has a twist - they must sing A Capella. 

This style of singing has become popular thanks to the movie franchise Pitch Perfect. 

After their amazing performance, viewers of the show took to Twitter to express just how good they are. 

Watch their amazing rendition here:

 

Is it better than the original?

 

Catch the group on The Naked Choir with Gareth Malone on Tuesday at 9pm.
