Watch Katy Perry perform ‘Roar’ and ‘Walking on Air’ on ‘SNL’

With just over a week until the release of “Prism,� Katy Perry took to “Saturday Night Live� over the weekend to perform two songs from the upcoming album. And the singer took quite a bit of gear with her, too.

For “Roar,� the new disc’s lead single, Perry converted the “SNL� stage into a leafy jungle like the one featured in the song’s video, while her band donned animal costumes straight out of some 4-year-old’s birthday party.

Later in the show (which was hosted by Bruce Willis), she traded the palm trees for flowing white curtains that gave the set something of a late-’80s/early-’90s nightclub look -- appropriate for the openly Technotronic-like vibe of “Walking on Air,� one of two additional songs (along with “Dark Horse�) that Perry has released ahead of “Prism’s� scheduled arrival on Oct. 22.

That day she’s set to perform an album-release show at Clear Channel Media’s new iHeartRadio Theater in Burbank, and on Oct. 23 she’ll headline a concert at the Hollywood Bowl benefiting the Young Survival Coalition, which “offers resources, connections and outreach� to “young women who are diagnosed with breast cancer,� according to its website. (Other acts on that bill include Ellie Goulding and Kacey Musgraves.)

Stay tuned this week to Pop & Hiss for a feature story on Perry and “Prism,� and watch “Roar� and “Walking on Air� below.
