Placido Domingo has been announced as the final closing act for Apple’s iTunes Festival London. Apple has also added a few more acts than what had been previously announced, to round out the lineup. This includes The Mirror Trap, Friend Within and the London Electronic Orchestra.

The month-long festival starts today at 9 PM UK time (1 PM PST), with ‘Deadmau5’ headlining Monday’s show. A full schedule can be found online at http://itunesfestival.com.

iPhone, iPad, Windows and Mac users can tune in to the gigs using the iTunes app. Videos of the performances will be streamed live as well as on-demand for free. If you live in the UK, you can still apply to win tickets to go to the event in person. The iTunes Festival is also being broadcast on Apple TV, with the dedicated app.
