Fashion week is defined as much by the music on the runway as it is by the clothes, and several designers in New York this week have moved from DJ’s spinning tracks to live performances for their shows.

Canadian alternative country music and rock band Cowboy Junkies played hits “Misguided Angel,” “Blue Moon” and “Sweet Jane” at the Ports 1961 show, while Brazilian singer Seu Jorge serenaded models on the runway at the Carlos Miele show.

But live music on the catwalk can cause complications.

Wearing a denim jumpsuit, Jorge initially was yelled at by photographers when he first walked on to the end of the runway. They didn’t realize he was performing and thought he was ruining their shot.

And during the final walk by all the models at the end of the show, one nearly fell after Jorge stood on the train of her evening dress. Maybe the models can teach him a thing or two about performing on the catwalk!

Designer Thuy Diep had a band play at an after party to celebrate her debut in New York Fashion Week’s Midtown Manhattan tents, and she hopes to take live music to the runway as well. “Definitely at some point I would love to have a live band or musician play at my show,” she told Reuters.

What musicians do you think would perform well on the catwalk?
