Stone Temple Pilots fronted by Bennington were the surprise act at Los Angeles radio station KROQ's Weenie Roast this past weekend. The band fired frontman Scott Weiland last December and has secretly been working with Bennington.

At the show they performed their debut song together, "Out of Time," along with a number of Stone Temple Pilots songs. After the show they released the song as a free download via Radio.com here.

KROQ's Kevin & Bean Show interviewed Bennington about the team-up following the performance and the singer revealed that they plan to carry on together. "We couldn't really plan a tour until tonight because we couldn't let people know what was going on," said Bennington. "Now the cat's out of the bag so we're going to go out and make more music and go play more shows and have some fun."

As for what attracted him to STP, Bennington revealed, "Every band has its own kinda vibe. Stone Temple Pilots has this sexier, more classic rock feel to it. Linkin Park is a very modern, very tech-heavy type of band.

"It was kind of nice. I got to use my voice tonight. I got to sing and show my range a little bit. I still got to through a little scream in here and there but it's really just so much different. I grew up listening to these guys. When this opportunity came up, it was just like a no-brainer."

On Monday morning an official announcement was sent out about the pairing that featured comments from the band and their new frontman.

"Chester has a one-of-a-kind voice that we've admired for a long time," said STP's Dean DeLeo. "We know Linkin Park will always be his priority, but we thought it would be cool to try something together. We managed to find the time to record a song and we're all really happy with the result."

"I've loved STP since I was 13 years old and they've had a huge influence on me," explained Bennington. "When the opportunity came up to do something creative with them, I jumped at the chance.
