Katy Perry will close out iTunes Festival

Apple is going all out this year with a star-studded line-up at its iTunes Festival—Katy Perry will close out the show, according to a story on AP.

With Lady Gaga opening the festival on September 1, and Katy Perry closing out the festivities 30 days later, Apple has secured two of Pop’s highest-ranking female stars. Both women recently released singles that are being well-received by fans, according to the latest Billboard charts.

iTunes Festival will also feature Elton John, Kings of Leon, Justin Timberlake and John Legend, among many others throughout the month-long concert series.

Held in London, England every September, the iTunes Festival features 30 days of free concerts. Tickets for the concerts are free on a lottery system for UK residents, but Apple also provides the shows free on iPhone, iPad and Apple TV for anyone to watch.
