Guitarist Dean DeLeo explained Bennington's double act on the band's website.
"Chester has a one-of-a-kind voice that we've admired for a long time,"
"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."
Bennington said he "jumped" at the chance to work with Stone Temple Pilots.
"I've loved STP since I was 13 years old and they've had a huge influence on me. When the opportunity came up to do something creative with them, I jumped at the chance. The guys in Linkin Park have been incredibly supportive of me undertaking this project while I've continued to work on new music with LP."
