The latest two events in Apple's global celebration of its 50th anniversary saw iPad artists take over the Sydney Opera House, while London danced at Apple Battersea.

Apple Battersea is both a store and Apple's UK headquarters, and the company often uses the iconic Battersea Power Station building in its marketing. To mark Apple's anniversary, huge Apple logos were projected on the building, and a stage was erected in front of it.

The evening saw London-based Nia Archives, award-winning DJ, singer and songwriter, playing jungle scene music. Apple says she's a "dedicated Logic Pro user", and has remixed for Jorja Smith, PinkPantheress, Jamie xx, and Fred again.

Alongside Nia Archives, Apple Battersea had a set from long-time Apple fans Mumford & Sons. They were introduced by Apple Music host Dotty, and performed hits plus tracks from their new album, Prizefighter.

Sydney Opera House

Just as Apple Battersea has previously done, Apple Australia has up with local artists and the public to create a visual event. This time the event was in celebration of the Apple anniversary, and it was a partnership with the Sydney Opera House.

The world-famous building was lit up by a series of artworks, six submitted by the public and 11 commissioned by Apple. Every piece was designed in the Procreate app on iPad.

This "Illuminating Creativity" project saw the opera house's eastern Bennelong sails transformed into a canvas. The moving artwork was accompanied by music from Logic Pro musician Bailey Pickles.

The UK and Australian events follow ones that have taken place all over the world. Apple is now expected to conclude its celebrations with a party at its Apple Park headquarters in California.
