Katy Perry will release her new album, Prism, Oct. 22.

Katy Perry has released her latest song “Walking On Air” from her upcoming album, Prism. She says she is aiming for a more mature sound on her fourth studio album.

“Another color from my #PRISM: WALKING ON AIR! Available NOW as part of my #PRISMPREVIEW!,” Katy tweeted.

That’s right, the Max Martin and Klas Åhlund production will probably not appear on the album. It’s just a sampling of the songs the 28-year-old singer intends to include.

Katy has already released two singles from the album her power-pop song, “Roar,” and more introspective tune “Dark Horse.”

While “Roar” will make the album, “Dark Horse,” featuring Juicy J, like “Walking on Air,” is promotional only. She’s also slated to release a second song from the album titled “Unconditionally.”

Katy is also partnering with Pepsi on the title.

The song is up-tempo with a dance beat as Katy sings about soaring into the stratosphere on a thrilling relationship. She sings:

Just when I think I can’t take anymore
We go deeper and harder than ever before
We go higher and higher
I feel like I’m already there
