Pentatonix's Scott and Mitch Reveal Their 'Legend Status' Favorite Celeb Musical Collaborations

Pentatonix members Scott Hoying and Mitch Grassi are still pinching themselves over the musical legends they've worked in recent years, despite being global multi-platinum artists themselves!

On Friday's episode of the PEOPLE Every Day podcast, vocalists Hoying and Grassi discussed their all-time favorite collaboration among a list of artists that includes Kelly Clarkson, Meghan Trainor, Dolly Parton, Jennifer Hudson, Miley Cyrus and Smokey Robinson.

"I would say Stevie Wonder. I mean, legend status. Everybody you named is a legend, but that was the one where I was like, 'I can't believe this is happening,'" Grassi, 30, tells PEOPLE. "And he sang flawlessly and that was one of my favorite performances we ever did too."

As for Hoying's choice? "The one person that like kind of stood out was Dolly Parton, just because she just feels like this untouchable goddess ... like, that we would never collaborate with," the 31-year-old says of the country legend, with whom they won a Grammy for their "Jolene" collaboration. "That was such an amazing experience and she was so professional and fun and sweet and warm. She didn't even act like a famous person sometimes acts — not at all for how legendary she is."

The a cappella group of five, which also consists of members Kirstin Maldonado, Kevin Olusola and Matt Sallee, are currently on a Christmas tour and have a special streaming on Disney+.

"We reached out to Disney a hundred thousand times because we all are such big Disney fans and it'd be our dream to have a special," Hoying says of the band's dream project.

The original concept, he says, was to travel to different countries, but they wound up having to do it virtually due to the pandemic.

"But it ended up being cute," he says. "We were like, did this whole concept where we're stuck in a mail room and then we virtually go to all these places."

"It was really cool to see different cultures and how they celebrate their holidays and how they create music," Hoying adds. "And collaborating with all these iconic artists was a dream come true."

Not to mention, the music is a natural fit for their talents and interests. "We all love Christmas," he says, "so it feels very authentic when we do it. And that's why we have '90 Christmas songs out —literally, that number!"

Despite the band being hugely in demand around the holidays, the main thing that Grassi says he looks forward to, during Christmas especially, is spending family.

"I always say that my favorite tradition is getting a break at the end of the year and spending time with my family and resting and eating," the Arlington, Tex. native shares. "You know, just soaking up that family time. It's really crucial."
