So I have heard this group on television for a number of their acts they performed. They have just won a Grammy for their song, “Daft Punk” which is a culmination of many different Daft Punk songs. If you never heard of Pentatonix, they are an a cappella group of five vocalists. Congratulations to Ben Bram, Mitch Grassi, Scott Hoying, Avi Kaplan, Kirstin Maldonado & Kevin Olusola. They really killed it. Check out the video below!
