Alesso, who will perform on the Ultra Music Festival main stage Sunday night (March 24) right before Swedish House Mafia's last set ever, took a moment out of his hectic weekend for a video interview with Billboard.com's Code column editor Kerri Mason. The young DJ/producer opens up about the pressure of playing before SHM at his Ultra gig tonight, working on his upcoming track with OneRepublic, and more. (Mobile users: watch here)

"I think that everybody that has anything to do with electronic dance music  is going to be there and watch it so there's a lot of pressure I think," Alesso says of playing before SHM at Ultra tonight. "But I'm going to go in there and do my thing and have fun." He shares that his set will include "new, unreleased stuff."

His upcoming song with OneRepublic, meanwhile, came about because "they sent a demo to me and I was like, 'whoa, I really want to do something with this,'" he says. "I worked with it in the studio every day for about a month. There was so much stuff I wanted to do with it. I wanted it to be still melodic and emotional like it is but still have energy. It was tough, but I'm pretty happy with it."

Alesso burst on the scene two years ago with a emotional remix of Starkillers’ "Pressure." Since then he’s distinguished himself as a master with vocals, through his hit festival tracks like "Years" with Matthew Koma, "Calling" with Sebastian Ingrosso and OneRepublic's Ryan Tedder, and "City of Dreams" with Dirty South and Ruben Haze.
