The five Utah dads who have recently been dominating YouTube have put a piano on top of a cliff, out on the Salt Flats and even on a moving train. Now, The Piano Guys take on another first: The first-ever concert special filmed at Red Butte Garden airs Thursday, Dec. 6 on PBS.---

For a little primer on The Piano Guys, go here. In short, they make YouTube videos showcasing Utah locales, which have received more than 160 million views. They grow 3,000 to 5,000 new YouTube subscribers a day and their channel gets 500,000 to one million views a day. Their overriding goal is to create music meant to uplift.

The concert special includes exclusive footage of the Sept. 19 Red Butte Garden concert. ThePianoGuys -- Steven Sharp Nelson on cello and Jon Schmidt on piano -- perform “Peponi,” an African version of Coldplay’s “Paradise” featuring singer Alex Boyé; their mash-up of the Bourne soundtrack with Vivaldi’s "Double Cello Concerto;" a brand-new cover of David Guetta’s “Titanium,” and many more.

The show airs at 8:30 p.m. on KUED.
