No matter the temperature, there'll be at least one person outside at Winterlude who can enjoy the festival in a t-shirt – the DJ.

2011's festival was the first to feature the Crystal Globe, an inflated, heated plastic bubble for performers.

It's back again this year in an expanded role, hosting the new "Sub-Zero Music Series" Friday and Saturday nights for the much more bundled-up spectators.

"We finish around 8 with (performers) and then we have a DJ every night until 10-10:30 p.m. so people can dance the night away," said Benoit Osborne.

Nelson Tagoona is a "throatboxing" artist (a mixture of beatboxing and traditional throatsinging) from Baker Lake, Nunavut.

He said he got great first impressions of the globe.

"It's amazing, it's somewhat unique," he said. "It creates a beautiful atmosphere and really brings the show."

Osborne said he likes to think of the Crystal Globe as an extension of the surrounding Crystal Garden.

"It looks like an ice carving when you think about it, with lights at night," he said. "People will be able to walk the grounds, see the beautiful carvings, and I think it almost looks like transparent ice."

As for Tagoona, he laughed when asked if he felt like he was performing in a giant plastic fishbowl.

"Yeah, I guess I'm the fish," he said.
