"It's a big responsibility," Brancowitz said in our latest Radio.com Essentials profile. "We know there's going to be a lot of people that are going to spend one hour each watching us. If it's a really bad moment, it's going to be like 60,000 hours wasted."

As headliners, the band certainly doesn't want to disappoint, but due to their past experiences at the fest they're having concerns. "We've played there twice," guitarist Christian Mazzalai said. "And we did maybe our worst show and our best show there."

"This time," Brancowitz interjected with a smile, "we aim for an average show." But as Daniel Glass, the President of the band's record label Glassnote Records, explained, these four guys — Brancowitz, Mazzalai, bassist Deck d'Arcy and singer Thomas Mars — don't do anything half-heartedly. For the last two months, Phoenix have been in seclusion getting ready for the live show, which will feature songs from their new album, Bankrupt!, out April 23. They've even hired a new lighting designer to echo the magnitude of the Coachella performance.
