A Capella group Pentatonix performs a beautiful rendition of “Hallelujah” that is sure to delight your musical senses. Leonard Cohen, a Canadian singer, and songwriter originally wrote “Hallelujah” and many different musicians and bands have since performed their cover version of it. I hope you enjoy the song. If you do like this music video and want to see another one from Pentatonix be sure to watch Carol of the Bells.
