See Katy Perry Sing With P.O.D. on 'Tonight Show' in 2006 Before She Was Famous

Nu-metal band and future pop star crossed paths on "Goodbye for Now"

Today, Katy Perry ranks as one of the biggest pop stars ever, but in 2006, she played her highest-profile performance to date, appearing on the Tonight Show not as the solo artist, but as a singer with San Diego nu-metal faves P.O.D.

At the time, Perry was still very much on the come up. She had first tried to make in the music biz as a Christian singer-songwriter under the name Katy Hudson. (Perry is the daughter of evangelical pastor Keith Hudson.) She eventually started using the Perry surname, and it was then that P.O.D. — themselves a Christian band — hooked up with the 21-year-old singer though producer Glen Ballard. The connection led to the 2005 collaboration "Goodbye for Now," featured on the group's sixth album, Testify. "We invited her to participate on our record as she was and is still is one of the few pop artists with strong musicianship roots," Marcos Curiel told Rolling Stone in 2015, responding to erroneous categorizations of Perry as their "backup singer."

In addition to contributing to the record, Perry also appeared in the single's music video, which you can view below. She later joined the band when they promoted Testify as the musical guests on the Tonight Show. It's a strange, surprising time-capsule moment for both her, looking very unlike the glamorous mega-star of "Firework" fame, and the dreadlocked nu-metal band. Watch above via YouTube.
