I love Pentatonix. Their vocals are always outstanding. This time they have outdone themselves. Their version of 'Say Something' is haunting and beautiful. I love the original by A Great Big World featuring Christina Aguelera, but I think this, just might top it.

Pentatonix is a 5-person vocal band from Texas that combines various genres such as pop, soul, R&B, and electronic music. They were the winners of season 3 of NBC’s ‘The Sing-Off.’
