Paul McCartney has officially prepared to perform at Apple Park for the 50th anniversary celebration of Apple. It has been reported that the legendary artist conducted a sound check at Apple's headquarters last night before the concert.

A user on Reddit shared an image from McCartney's sound check last night.

The former Beatles member and the rest of his band can be seen on the rainbow stage within the Apple Park ring. The rainbow structure has been transformed into a real concert environment with stage lights. There are large screens on both sides of the stage, ensuring that everyone in the crowd has a great view.

It has been reported that Apple employees did not receive a guest invitation for the McCartney concert, indicating that the event will be limited to Apple employees only.

The concert will take place tonight, ahead of Apple's official 50th anniversary celebration. This is part of a few weeks of celebrations featuring performances by artists like Alicia Keys at Apple Grand Central in New York City and Mumford & Sons at Apple Battersea in London.

There is still no information on whether Apple will record the Paul McCartney concert and make it available to the general public.
