Whilst the likes of Boards of Canada and Daft Punk prefer lengthy/mysterious campaigns in the lead-up to new album announcements, Katy Perry goes all in, hiring a gold semi-truck to drive through LA with 'Katy Perry - Prism - 10/22/13' written on the side.

The singer tweeted the following last night:

The image that you can see above was shot by Adam Lambert, though if you do a quick twitter search, you'll find hundreds of similar images to gaze over.

The follow-up to 2010's Teenage Dream is expected to feature Max Martin, Dr Luke and Greg Wells on the collaborators table, and will be released on October 22nd via Capitol.
