Darren Criss Interview: "Hedwig," Life After "Glee" & New Music

Elsie Fest, which is anticipated to return on an annual basis, is the brainchild of Criss, the Emmy-nominated musician/actor/composer and star of Glee; talent manager Ricky Rollins and Broadway producer and Jujamcyn Theaters president Jordan Roth.

“I was at Coachella and thought ‘let's do this for showtunes,'” comments Criss in a statement. “Musical theater has been going through a wonderful shift in the past few years, from the type of work that’s being produced to the way it’s being consumed by the public. It's more than showtunes on Broadway -- it’s songs from film, TV and YouTube. Since the rules were already changing, I figured, why not shake up people’s ideas of where to watch the performers they love. Enter Elsie.”
