7 Reasons You Should Love Pentatonix

The Season 3 winner of the The Sing-Off.

This is Pentatonix

To know them is to love them. To love them is to call yourself a Pentaholic. (from l to r) Kevin 'K.O' Olusola, Mitch Grassi, Kirstie Maldonado, Scott Hoying, and Avi Kaplan.

1. They take songs you kinda, sorta like and do amazing a cappella arrangements that you can't forget

Their most recent cover is of 'Radioactive' by Imagine Dragons and features pop-violinist Lindsey Stirling.

2. Scott Hoying can do vocal riffs your mind can not fathom

Scott, for all intents and purposes, is the frontman of the group. If vocal power was measured in wattage, he'd be able to power Manhattan.

3. Mitch Grassi has the voice of an angel

Dubbed 'the prettiest voice I've ever heard' by Boys 2 Men's Shawn Stockman, Mitch can take you to heaven and back. (video features a brief Kevin intro)

4. Kirstie Maldonado is nobody's underdog

The lone female in the group, Kirstie is a force not to be reckoned with. Because she will destroy you. All that power in a small, humble package. She gives you life and you never see it coming.

5. Kevin Olusola beatboxes and plays the cello...at the same damn time

Don't even get me started on how versatile this man is. You want cello? Okay. You want trumpet? He can do that. You want a dubstep beat drop? Let him get a drink of water first and then he has you. You need a rap verse? He'll spit it, while keeping the percussion going.

6. Avi Kaplan can do overtones and jump octaves in a single breath

Overtones are essentially singing two notes at the same time (Yes, you read that correctly), which makes for an incredible sound. Not only that, Avi's operatically trained bass cannon sounds great in the second octave or the third (and his speaking voice seems to drive everyone mad).

7. They don't just do covers

This is one of their original songs off the first EP, 'PTX, Vol. 1' called 'Baddest Girl.'
