The Fray will be on the road through summer in support of their breakout Epic debut, "How To Save a Life," which has spawned two top 10 hits on the Billboard Hot 100 and shifted more than 1 million copies in the United States, according to Nielsen SoundScan. Guitarist Joe King tells Billboard.com the group will tour college markets in the spring, followed by its biggest outing to date in amphitheatres during the summer.

"I'm really nervous actually, because it's a whole new level of touring," he says. "This fall tour was a massive step for the Fray, with production, crew and capacities. But summer will probably be four times that."

"There are two different battles you're waging when you play that size of a venue," vocalist/pianist Isaac Slade adds. "One is just getting through it and not freaking out and peeing your pants. We've actually gotten to the point where we're all pretty comfortable. But the trick is capturing everybody's attention for that long in such a big place."

Owing to the fact that there's only one album's worth of material to play, the Fray have begun sprinkling new songs into the live set list. King takes the mic for "Uncertainty," which has been around in some form since before he was a member of the Fray but has been brought back to life of late. "The song is really about the uncertainties of life and living with the unexpected," he says. "Nothing is guaranteed. You may feel safe, but then your world collapses."

Fans are already going wild for "Absolute," which features a section that Slade has yet to write lyrics for. Live, he just mumbles through it, but that hasn't stopped people from trying to decipher what he's saying. "Somebody came up to our bass player and told him he transcribed it off of YouTube," he says with a laugh. "But there's literally no words. This guy actually transcribed our gibberish."

A third new tune, "Happiness," was penned by Slade "when my wife was long-distance. We were engaged and trying to plan everything. I was thinking about how happiness can make you sad," he recalls. "I think there's a real disparity in our culture between now actions and tomorrow consequences. It's like this delayed gratification thing."

In between the spring and summer tours, King and Slade plan to "just go up to the mountains and seclude ourselves in a little cabin" to work on more ideas for album number two. "I can definitely say I feel like we have evolved in a writing sense. I'm not really worrying about single or hit material. We just write. If it catches us, we'll keep going with it."
